Dual-Channel Line Card CODEC
This version: Dec. 2001 Previous version: Jul. 2001
GENERAL DESCRIPTION
The ML7033 is a 2-channel PCM CODEC CMOS IC designed for Central Office (CO) and Customer Premise Equipment (CPE) environments. The ML7033 device contains 2-channel analog-to-digital (A/D) and digital-toanalog (D/A) converters with multiplexed PCM input and output. The ML7033 is designed for single-rail, low power applications. The high integration of the ML7033 reduces the number of external components and overall board size. The ML7033 is best suited for line card applications and provides an easy interface to subscriber line interface circuits (SLIC's), in particular the Intersil RSLICTM series.

FUNCTIONAL DESCRIPTION
Pin Functional Description AIN1N, AIN1P, AIN2N, AIN2P, GSX1, GSX2 The AINnN and AINnP pins are the transmit path analog inputs for Channel-n, where n equals channel 1 or channel 2. The AINnN pin is the inverting input, and the AINnP pin is the non-inverting input for the op-amp. The GSXn pin functions as the transmit path level adjustment for Channel-n and is connected to the output of the op-amp. It is used to adjust the output level as shown in Figure 8 below. When the AINnN or AINInP pins are not in use, connect the AINnN pin to the GSXn pin and the AINnP pin to the SGC pin. During power-down mode, the GSXn output is in a high impedance state. In the case of the analog input 2.226 Vpp at the GSXn pin, the digital output will be +3.00 dBm0.

Example of Analog Input Setting Schematic
AOUT1P, AOUT1N, AOUT2P, AOUT2N The AOUTnN and AOUTnP pins are the receive path analog outputs from Channel-n, where n equals channel 1 or channel 2. These pins can drive a load of 20 k or more. When the AOUTnSEL register bit (CR7-B7/CR14B7) is cleared (0), the AOUTnP pin is a single-ended output from Channel-n and the AOUTnN pin is at high impedance. When the AOUTnSEL bit is set (1), the AOUTnN and AOUTnP pins are differentials outputs from the corresponding channel. The output signal from each of these pins has an amplitude of 3.4 Vpp above and below the signal ground voltage (SG). Hence, when the maximum PCM code (+3.00 dBm0) is input to the PCMIN pin, the maximum amplitude between the AOUTnN pin and the AOUTnP pin will be 6.8 Vpp. While the device is in power-down mode, or the corresponding channel (1 or 2) is in power saving mode, the related outputs are high impedance. Refer to Table 5 for more information.

TOUT1, TOUT2 TOUTn is the tone analog output for the corresponding channel. The output signal has an amplitude of 2.5 Vpp above and below the signal ground voltage (SG). While the device is in power-down mode, or the corresponding channel is in power-save mode, the related outputs are high impedance. VDDA, VDDD +5 V power supply for analog and digital circuits. The VDDA pin is the power pin for the analog circuits. The VDDD pin is the power pin for the digital circuits. If these signals are connected together externally, The VDDA pin must be connected to the VDDD pin in the shortest distance on the printed circuit board. Internal to the ML7033, the VDDA plane is separate from the VDDD plane. To minimize power supply noise, a 0.1 F bypass capacitor (with excellent high frequency characteristics) and a 10 F electrolytic capacitor should be connected between the VDDA pin and the AG pin. In addition, the same capacitive network should also be connected between the VDDD pin and the DG pin. If the AG and DG pins are connected together externally, only one capacitive network is required. AG, DG The AG pin is a ground for the analog circuits. The DG pin is a ground for the digital circuits. The analog ground and the digital ground are separated internally within the device. The AG pin and DG pins must be connected in the shortest distance on the printed circuit board, and then to system ground with a low impedance. SGC The SGC pin used is to internally generate the signal ground voltage level by connecting a bypass capacitor. The output impedance is approximately 50 k. Connect a 0.1 F bypass capacitor with excellent high frequency characteristics between the SGC pin and the AG pin. During power-down mode, the SGC output is at the voltage level of the AG pin. SG The SG pin is the signal ground level output for the system circuits. The output voltage is 2.4 V, the as same as the SGC pin in a normal operating state. During power-down mode, this output is high impedance. MCK Master clock input. Input either 2.048 or 4.096 MHz clock. After turning on the power, the appropriate value must be written into the MCKSEL bit (CR0-B5) depending upon the desired master clock frequency. If the supplied master clock frequency and the value of the MCKSEL bit (CR0-B5) do not match, the powerdown control circuit and the MCU interface circuit will continue to operate properly. Access to the control registers can also occur. However, other circuits may not operate properly. As for the power-on sequence, please refer to "Power-On Sequence" in the later page.

BCLK Shift clock signal input for the PCMIN and the PCMOUT signals. The clock frequency, equal to the data rate, is 256 kHz to 4096 kHz. This signal must be generated from the same clock source as the master clock and synchronized in phase with the master clock. Please refer to Figures 1 and 2 for more information about the phase difference between MCK and BCLK. RSYNC Receive synchronizing clock input. The PCMIN signals are received in synchronization with this clock. The 8 kHz input clock is generated from the identical clock source as MCK and must be synchronized in phase with the master clock. XSYNC Transmit synchronizing clock input. The PCMOUT signals are transmitted in synchronization with this clock. The 8 kHz input clock is generated from the identical clock source as MCK and must be synchronized in phase with the master clock. PCMIN Serial PCM data input. The serial PCM data input on the PCMIN pin is converted to analog signals and output from the AOUTnP pin (or from the AOUTnN pin and the AOUTnP pin) in synchronization with the RSYNC clock and the BCLK clock. When in Long Frame Sync Mode (CR0-B4 = "0"), the first bit of the serial PCM data (MSD of channel 1) is identified at the rising edge of the RSYNC clock. When in Short Frame Sync Mode (CR0-B4 = "1"), the first bit of the serial PCM data (MSD of channel 1) is identified at the falling edge of the RSYNC clock. PCMOUT Serial PCM data output. Channel 1 data is output in sequential order, from most significant data (MSD) to least significant data (LSD). Data is synchronized with the rising edge of BCLK. When in Long Frame Sync Mode (CR0-B4 = "0"), the first bit of PCM data may be output at the rising edge of the XSYNC signal, depending on the timing between BCLK and XSYNC. When in Short Frame Sync Mode (CR0-B4 = "1"), the first bit of PCM data may be output at the falling edge of the XSYNC signal, depending on the timing between BCLK and XSYNC. This pin is in a high impedance state during power-down. A pull-up resistor must be connected to this pin since it is an open drain output. PCMOSY PCMOSY is asserted to a logic 0 when PCM data is valid on the PCMOUT pin. This includes both normal mode and power-save mode. When PCM data is not being output from the PCMOUT pin (including during power-down mode), this pin goes a logic "1". This signal is used to control the TRI-STATE Enable of a backplane line-driver.

PDN Power-down control signal. When PDN is a asserted (logic "0"), both the channel 1 and channel 2 circuits enter the power-down state. However, even in power-down mode, the state of the control registers is maintained. Reads and writes to the registers are also possible, and the state of the INT pin also changes in accordance with inputs from the SLIC devices. This pin is deasserted (logic "1") by external logic during normal operation. This power-down function is available even in power saving mode by the MODEn (CR0-B1/CR0-B0) bit. RESET An input to reset control registers. By asserting the RESET pin (applying a logic "0"), all control registers are initialized. During a normal operation mode, set this pin logic "1". Table 3

F2_1, F1_1, F0_1, F2_2, F1_2, F0_2 The F2_n, F1_n and F0_n pins are data outputs used when the SLIC connected to the corresponding channel is an Intersil RSLICTM series device. The output levels from the F2_n, the F1_n and F0_n pins are determined by the F2_n, F1_n, and F0_n register bits (CR6-B7 to B5 and CR13-B7 to B5). By inputting these outputs directly into the corresponding input pin of the SLIC device, the SLIC operating mode selection is possible. Even in the power-down state with the PDN pin is asserted, these pins remain functional. E0_1, E0_2 The E0_n pins are the detector mode selection data outputs. These pins are used when the SLIC connected to the corresponding channel is an Intersil RSLICTM series device. Though the output level from the E0_n pin is determined by the E0_n bit (CR6-B2/CR13-B2), the output level changes in 20 s (= hold timer) in the poweron mode with the PDN pin = logic "1" and in 200 ns in the power-down mode with the PDN pin = logic "0" after the change of E0_n bit (CR6-B2 /CR13-B2). Refer to Figure 6 for information. What event is actually detected by the SLIC is determined by the combination of the F2_n, F1_n, F0_n and E0_n pins. Refer to Table 6 for more information. By connecting the output directly into the corresponding input pin of the SLIC device, detector mode selection in the SLIC is possible. Even in the power-down state with the PDN pin = logic "0", this pin remains functional. However, the hold timer is ignored in this state.

BSEL1, BSEL2 The BSELn pin is the battery mode selection data output. This pin is used when the SLIC connected to the corresponding channel is an Intersil RSLICTM series SLIC device. A logic "0" on this pin selects the low battery mode, and the logic "1" selects the high battery mode within the SLIC device. The output levels from the BSELn pins are determined by the BSELn register bits (CR6-B3/CR13-B3). By connecting these outputs directly to the corresponding SLIC device input pins, battery mode selection of the SLIC is possible. This pin remains functional even in power-down mode. SWC1, SWC2 The SWCn pin is the uncommitted switch control data output. This pin is used when the SLIC connected to the corresponding channel is an Intersil RSLICTM series SLIC device. By connecting this pin directly to the corresponding input pin of the SLIC device, the uncommitted switch control can be made. The uncommitted switch is located between the SW+ pin and the SW- pin. A logic "0" on this pin enables the SLIC internal switch on, and a logic "1" disables the switch. The output levels from the SWC1 and SWC2 pins are determined by the SWCn register bits (CR6-B4/CR13B4). This pin remains functional even in power-down mode with the PDN pin is a logic "0". DET1, DET2 The DETn pins are the SLIC's detection signal (switch hook, ring trip or ground key detection) inputs. These pins are used when the SLIC connected to the corresponding channel is an Intersil RSLICTM series device. A logic "0" on this pin clears the corresponding DETn register bit (CR6-B1/CR13-B1). A logic `1' on this pin input sets the register bit. The Intersil RSLICTM series SLIC device is equipped with a function to switch the output on its DET pin from a logic "1" state to a logic "0" state when it detects an assigned event of either off-hook, ring trip or ground key. Therefore, by connecting these pins to the corresponding pins on the SLIC device and reading the DETn register bit (CR6-B1/CR13-B1), the occurrence of an assigned event can be detected.

ML7033
The event detected by the SLIC is determined by the F2_n, F1_n, and F0_n register bits (CR6-B7 to B5/CR13B7 to B5), and the E0_n register bits (CR6-B2 /CR13-B2). To avoid the unintended detection of these conditions due to glitches on the DETn signal of the SLIC, the ML7033 is equipped with a debounce timer to hold the DET register bit (CR6-B1/CR13-B1) and the output of the INT pin for a set period, even when an input to the DETn pin changes from a logic "1" to a logic "0". For more information on the debounce timer, refer to the DETnTIM3 through DETnTIM0 register bit descriptions (CR4-B7 to B0). This pin remains functional in power-down mode (PDN pin low). However, while in the power-down state, the debounce timer is disabled. When this pin is not used, it should be tied to VDDD. ALM1, ALM2 The ALMn pins are the thermal shut down alarm signals. These pins are used when the SLIC connected to the corresponding channel is an Intersil RSLICTM series device. A logic "0" on the ALMn input pin clears the corresponding ALM register bit (CR6-B0/CR13-B0). A logic "1" on this pin sets the bit. The Intersil RSLICTM series device is equipped with a function that allows it to automatically enter power-down mode and toggle its ALMn pin from a logic "1" to a logic "0" state when the SLIC die temperature exceeds a safe operating temperature. Hence, by connecting the corresponding pin of the SLIC device to the ALM1 and ALM2 pins and reading the ALM register bit (CR6-B0/CR13-B0), it is possible to know whether the concerned SLIC device is operating normally, or is in a thermal shutdown state. This pin remains functional in power-down mode. However, while in the power-down state, the debounce timer is disabled. When this pin is not used, it should be tied to VDDD. INT The ML7033 asserts the INT interrupt pin when either the DETn pin or the ALMn pin are asserted by the SLIC device when the device is an Intersil RSLICTM series SLIC device. The Intersil RSLICTM series device is equipped with detector and thermal shut down alarm functions to notify a change of SLIC state by driving a logic 0 onto the output pins connected to DETn and ALMn. Refer to the DETn and ALMn pin descriptions above. By monitoring the state of the INT pin and reading the DETn (CR6-B0/CR13-B0) and ALMn (CR6B0/CR13-B0) register bits, it is possible to know that a change of a state occurred within the SLIC device. The INT pin transitions from a logic "1" to a logic "0" in the following cases; (1) (PDN pin = logic "0") Any of the ALMn or DETn pins in the logic "1" state transition to the logic "0" state. (2) (PDN pin = logic "1") Any of the ALMn or DETn pins transition from the logic "1" state to the logic "0" state when all the four pins (ALM1, ALM2, DET1, and DET2) have been in the logic "1" state. Note that the debounce timer with the DETn pin is not valid while in power-down mode (PDN pin = logic "0").

The INT pin is released to the logic "1" state in either of the following cases; (1) (PDN pin = logic "1") Any one of the ALMn or DETn pins in the logic "0" state transition to the logic "1" state. (2) (PDN pin = logic "0") All of the ALMn or DETn pins in the logic "0" state transition to the logic "1" state. (3) Both SLIC 1 control (CR6 register) and SLIC 2 control (CR13 register) are read by the MCU. Note that the debounce timer, which works when the DETn pin changes from a logic "1" state to a to logic "0" state, does not work when the pin changes from logic "0" to logic "1". DEN, EXCK, DIO Serial control ports for the MCU interface. These pins are used by an external MCU to access the internal control registers of the ML7033. The DEN pin is the data enable input. The EXCK pin is the data shift clock input. The DIO pin is the address and data input/output. Figure 9 shows the MCU interface input/output timing diagram.

The CIDATA1 and CDATA2 data inputs are used for Caller ID generation. While in a Caller ID tone generation mode with the CIDCHnON register bit set, (CR1-B1/CR1-B0), signals on the CIDATAn pins are modulated in either the ITU-T V.23 or Bell 202 schemes. The scheme is determined by the CIDFMT register bit (CR1-B2), and output from the analog output pin(s). The analog output pins for modulated Caller ID data can be selected by the CHnTG2TX (CR7-B6/CR14-B6), the CHnTGTOUTn (CR7-B5/CR14-B5), and the AOUTnSEL (CR7-B7/CR14-B7) register bits. The output level for the modulated Caller ID data can be tuned by the CHnTG1LVn (CR9-B7 to B1/CR16-B7 to B1) register bits. TEST The TEST input is used for testing purposes only during the manufacturing process and has no function once the testing process is completed. This pin is not used during normal operation of the device and should be kept at a logic "0" state.

Power-On Sequence While in the power-on state, the following chart is recommended.
POWER OFF As the ML7033 is equipped with a power-on reset function, initialization of the control registers automatically occurs as the power is turned on, even with the RESET pin = logic "1". However, if any of input pins are not in a high impedance state, the power-on reset may not function properly. Keep the input to the RESET pin in the logic "0" state for 100ns or longer before changing to a logic "1".
Power supply on PDN pin = logic "0", RESET pin= "0"
RESET pin = "0" to "1" (or Power-on Reset Function)

PDN pin = "1"
Even during power-down mode with the PDN pin = logic "0", the SLIC interface registers (CR6, CR13) and the INT pin are working. Data set in other registers becomes valid after the PDN pin is driven to a logic "1" state.

Time slot assignment channel select 0 : CH1 1 : CH2 This bit is used to specify the channel for which the accompanied TSAn (CR3-B5 to B0) bits are going to assign a time slot. Hence, when a customized time slot assignment is enabled, CR3 should be written twice; once for CH1 and another for CH2. ... Assigned time slot select Each time slot consists of 8 BCLK cycles. The number of time slots available for time slot assignment depends upon the applied BCLK frequency, and can be calculated in the following equations; Number of time slots available for time slot assignment = (BCLK frequency)/(SYNC frequency)/8 = (BCLK frequency)/64k For instance, when the BCLK frequency is 4096 kHz, time slots that can be assigned are from 0 (000000) to 63 (111111). The specification of a time slot beyond 63 is prohibited. Note that in 14-bit linear PCM (2's complement) mode, specified when the LIN bit (CR0B3) is set, only even numbered time slots (0, 2, 4, ... 62) can be assigned. In any mode, the assigned time slot for a channel is common both for transmit and receive, and different time slots cannot be assigned for transmit and receive. When the TSAE bit (CR3-B7) is cleared, the time slot assignment specified by these bits is ignored, and the default time slots are assigned (CH1 for Time Slot 0 and CH2 for Time Slot 2). Figure 12 shows an example of how CH1 is assigned for Time Slot 0 (000000) and CH2 is assigned for Time Slot 3 (000011) in 8-bit PCM mode.

... Debounce timer setting for CH2 ... Debounce timer setting for CH1 To avoid the unintended detection of glitches on the DETn signal, the ML7033 is equipped with a debounce timer to hold the DETn (CR6-B1/CR13-B1) bit and the INT output state for a set period, even when the state of the DETn pin changes from logic "1" to logic "0". Bits B7 to B4 determine the debounce timer setting for CH2. Bits B3 to B0 determine the debounce timer setting CH1. The debounce timer is operational only in the power-on state when the PDN pin = logic "1", and remains operational in the power-saving mode with the MODEn (CR0-B1, B0) bits = "0" as long as the device is in the power-on state. The debounce timer holding time ranges from 0 ms to 225 ms at 15 ms intervals for each individual channel. The values written into B7 to B4 (channel 2) or B3 to B0 (channel 1) determine the holding time for each channel. The timer value is calculated by the equation of [Decimal(B7,B6,B5,B4) * 15] or [Decimal(B3,B2,B1,B0) * 15]. Refer to Table 8. Table 8

... Event detection indicator for SLIC1 (Read-only bit) 0 : detected 1 : not detected By reading the state of this bit, the input level to the DET1 pin can be known. If this bit is cleared it indicates that the DET1 pin is in the logic "0" state. If this bit is set it indicates that the DET1 pin is in the logic "1" state. When the SLIC connected to channel 1 is from the Intersil RSLICTM series, the DET1 pin can be connected directly to the corresponding output pin of the SLIC device. This allows an assigned event such as off-hook, ring trip, or ground key to be detected. The event detected by the SLIC detects is determined by the F2_1, F1_1, F0_1 (CR6-B7 to B5), and E0_1 (CR6-B2) bits. When the debounce timer is enabled by setting the DET1TIM3 through DET1TIM0 bits (CR4-B3 to B0), the DET1 (CR6-B1) bit is held unchanged for a set period, even when the DET1 input pin changes from logic "1" to logic "0".

... Operation mode setting for SLIC2 This 3-bit field determines the output level of the Fn_2 pins. For more detail, refer to Table 6. When any of these bits are cleared, the corresponding Fn_2 pin outputs a logic "0". When any of these bits are set, the corresponding Fn_2 pin outputs a logic "1". ... Uncommitted switch control for SLIC2 0 : switch on 1 : switch off This bit determines the output level of the SWC2 pin. When this bit is cleared, the SWC2 pin outputs a logic "0". When this bit is set, the SWC2 pin outputs a logic "1". When the SLIC connected to channel 2 is an Intersil RSLICTM series device, the internal uncommitted switch of the SLIC, located between the SW+ and the SW- pins, can be controlled by connecting the SWC2 pin directly to the corresponding input pin of the SLIC device.

... Event detection indicator for SLIC2 (Read-only bit) 0 : detected 1 : not detected By reading the state of this bit, the input level to the DET2 pin can be determined. If this bit is cleared, the DET2 pin is a logic "0". If this bit is set, the DET2 pin is a logic "1". When the SLIC connected to channel 2 is an Intersil RSLICTM series device, an assigned event of off-hook, ring trip or ground key can be detected by connecting the DET2 pin of the ML7033 directly to the corresponding output pin of the SLIC device. The event detected by the the SLIC is determined by the F2_2, F1_2, F0_2 (CR13-B7 to B5), and E0_2 (CR13-B2) bits. When a debounce timer is enabled by a setting with the DET2TIM3 through DET2TIM0 bits (CR4-B7 to B4), the DET2 (CR13-B1) bit is held unchanged for a set period, even when the DET2 pin changes from a logic "1" to a logic "0".
