Semiconductor SA0, SA1
MSM6895/6896
Sounder (ringing tone) driving outputs. The output signal on SA1 is inverted against the signal on SA0. The sounder circuit can be easily configured by connecting a piezo-sounder between SA0 and SA1. Through processor control, the ringing tone volume is selectable from four levels and one of six tone combinations is selectable. Initially, the ringing tone volume is set at a maximum and the tone combination is set externally. If these pins are used with no-load, tone volume cannot be controlled. When tone volume control is required, a load resistor must be connected between SA0 and SA1.
RMI, RMO0, RMO1 Receive main amplifier input and outputs. RMI is the main amplifier input and RMO0 and RMO1 are the main amplifier outputs. The output signal on RMO1 is inverted against RMO0, so the earphone of a piezo electric-type handset is directly connected between RMO0 and RMO1. The RMI input pin is connected to the receive preamplifier output pin (RPO). If the adjusting of receive path frequency characteristics is required, insert the following circuit for adjustment. During initial setting, the speech path from RMI to RMO0 and RMO1 is disconnected and the output of RMO0 and RMO1 is at the VSG level (VA/2). The speech path is provided by processor control.

R2
SPO Output of preamplifier for speaker. Since the driving capability is 2.4 VPP for the load of 20 kW, SPO can not directly drive a speaker. During initial setting, SPO is in a non-signal state (VSG level), and a speech signal, RTONE0, RTONE1, FTONE, hold acknowledge tone, and PB signal acknowledge tone are output through processor control.
7/43
Semiconductor R1I, R2I, RPO
MSM6895/6896
Receive preamplifier inputs and output. R1I and R2I are for the inputs and RPO is for the output of the receive preamplifier. Normally, R1I is connected via an AC-coupling capacitor to the CODEC analog output (CAO), and R2I is used as the mixing signal input pin. During initial setting, the RPO output is in non-signal state (VSG level), and speech signal, RTONE1, RTONE2, FTONE, PB acknowledge tone, and side tone signal are output through processor control. And if the three-party speech function is required, the R2I pin is connected to the analog output of the other CODEC.
MLDY Hold tone signal input. This pin is connected to the output of external melody IC. Through processor control, the signal applied to MLDYI is output from the TO output pin as a hold tone on the transmit path, and from the SPO output pin as a hold acknowledge tone on the receive path.
TPBI Transmit signal input. When the handset is used, TPBI is connected to the transmit preamplifier output pin (TPAO). If adjustment of frequency characteristics on the transmit path is required, insert a circuit for adjustment of characteristic between TPAO and TPBI. Through processor control, the signal applied to this pin is output via the T1O and T2O pins on the transmit path output and its side tone via the RPO pin.

TMX1I, TMX2I Transmit addition signal inputs. Through processor control, the input signals to TMX1I and TMX2I are added to the transmit signal and are output to T1O and T2O respectively.
8/43
Semiconductor TPAI, TPAO
MSM6895/6896
The transmit preamplifier input and output. TPAI is the input and TPAO is the output. Connect TPAI to the microphone of handset via an ACcoupling capacitor if the DC offset appears at a transmit signal (offset from SGT). The transmit path from TPAI to TPAO is always established regardless of processor control.
VSG Signal ground level output. The output level is equal to a half of the power supply voltage.
VSGC Bypass capacitor connecting pin for signal ground level. Insert a 0.1 mF capacitor with good higher frequency characteristic, between VSGC and VAG.
VA, VD +5 V power supply. VA is for an analog circuit and VD is for digital supply. Connect both VA and VD to the +5 V analog path of the system.
CAI CODEC analog output. Connect CAI to T1O.
CAO CODEC analog output. Connect CAO to R1I via an AC-Coupling capacitor.

Semiconductor TEST, CK1536
MSM6895/6896
External master clock inputs. Since the MSM6895 and MSM6896 contain PLL internally, the external clock signal is eliminated. But the device can operate with the external clock through these pins. When these pins are not used, leave these pins open or at 0 V.
Mode Internal PLL External master clock TEST pin 0V Digital "1" CK1536 pin open or 0 V Input the signal of 1536 kHz
When the external clock is used, the CK1536 signal is required to be synchronized in phase with the CK8 signal.
CK64 CODEC PCM data input and output shift clock input. When the continuous clock is set, the frequency is one of 64 kHz, 128 kHz, and 256 kHz. When the burst clock is used, one of 192, 384, 768, 1536, and 2048 kHz is available. If the BCLOCK signal is not applied, PLL is out of synchronization and goes into the self-running mode.
CK8 Synchronous signal input. CODEC PCM data is sent out sequencially from MSB at the rising edge of the CK64 signal in synchronization with the rise of the synchronous signal. PCM data should be entered from MSB in synchronization with the rise of the synchronous signal. PCM data is shifted in at the falling edge of the CK64 signal. Since the CK8 signal is used for a trigger signal for PLL and for a clock signal to the tone generator, if this signal is not applied, not only any tone can not be output, but also PLL goes out of synchronization and goes into self-running mode. This signal has to be synchronous with the CK64 signal and its frequency must be within 8 kHz 50 ppm to ensure the CODEC AC characteristics (mainly frequency characteristics). LOSS Signal output for controlling the external circuits. When the howler tone of sounder is selected through processor control, the output is in a digital "1". Initially, this output is set to a digital "0".

Semiconductor PO0, PO1, PO2, PO3, PO4, PO5, PO6, PO7
MSM6895/6896
Key scanning outputs. These output pins need external pull-up resistors because of their open- drain circuits. Through processor control, these outputs can be set open or to digital "0". Initially, these outputs are set at an opened state.
PI0, PI1, PI2, PI3, PI4, PI5, PI6, PI7 Key scanning inputs. In the READ mode, data on PI0 to PI7 can be read out of the processor via data bus (DB0 to DB7).
INTT Interrupt signal output to the processor. INTT outputs interrupt signals (digital "0") at intervals of 8 ms by the interrupt release control signal from the processor. INTT does not output any signal while no CK8 signal is input.

Control of channel selector Key scanning output control, interrupt release control Volume control and tone combination control of sounder CODEC power down control Level control of transmit path, PB tone, and Hold tone, Gain control of receive path Frequency control of howler tone Read of the key scanning data Function
WR Write signal for internal control registers. Data on the data bus is written into the registers at the rising edge of WR under the condition of digital "0" of CE (Chip Enable). While CE is in digital "1" state, WR becomes invalid. The Write cycle is a minimum of 2 ms, but if the CK64 and CK8 signals are silent, the write cycle requires a minimum of 50 ms. A minimum of 2 ms specified as the write cycle is valid 10 ms after CK64 and CK8 signals are input. RD Read signal input to read PI0 to PI7 out of the processor. When CE and RD are in digital "0" state, the digital values on PI0 to PI7 are output onto the data buses DB0 to DB7. While CE is in digital "1" state, the RD signal becomes invalid.

Semiconductor CE Chip Enable signal input. When CE is in digital "0" state, WR and RD are valid.
MSM6895/6896
B1T, B2T, B1R, B2R B channel interface inputs and outputs. B1T and B2T are outputs, and B1R and B2R are inputs. Through channel control by the processor, various data paths are set. The CODEC input and output signals are input and output via these pins. Initially the B1T and B2T outputs are fixed in a digital "1", and the B1R and B2R inputs are neglected.
BR1, BR2, BT1, BT2 External digital inputs and outputs to the B-channel. BR1 and BR2 are outputs, and BT1 and BT2 are inputs. Through channel control by processor, the digital paths are set between these input and output pins and the B channel. These signals are applied to another CODEC interface of three-party the speech path and to the interface of 64 kbps at the rate adaptor circuit. Initially the BR1 and BR2 outputs are fixed in a digital "1", and the BT1 and BT2 inputs are neglected. RESET Reset signal input. Digital "0" input to RESET makes all of internal control registers to be initialized. When powered on, this RESET signal should be input for initializing the system. TIME Watchdog timer output. When the processor does not reset the timer, the 500 ms period (Digital "0" : 4 ms) digital signal is continuously output. When RESET is at digital "0", this timer is reset. And, in about 500 ms after RESET goes to digital "1", the first timer output signal is issued and then the timer signal is output at intervals of a 500 ms. If the CK8 signal is not input, the TIME signal is not output.
LML Control signal output for external hold tone generator. LML goes to digital "1" state when the hold tone transmit mode on transmit path or the hold acknowledge tone mode on receive path is selected. During initialized state, LML is in digital "0" state.

PDC: This bit is used for the CODEC power-down control. For making this bit valid, "0"s must be written to the control data bits described in the later section. PDC = 1: CODEC is in power-down mode. PDC = 0: CODEC is in operation mode. When the HOW is indicated, the LOSS output is "1". Otherwise it is "0". In the above specification, the data contents written later are valid. The signal of sounder path (SA0, SA1) and the signal of receive path (RPO) can not be output simultaneously.

NTTC = 1 when the initial state is set. NTTC can be set as PBTC when the PB tone is set, but the data written into NTTC in later is valid. When NTTC = 1, the FTONE (1) and FTONE (2) signals are output from SPO. When NTTC = 0, these signals are output from RPO. NTTC = 1 when FTONE and PB tone is stopped. When two or more signals are specified out of IIT, T250 and FTONE, the output signals are compounded by two or three tones. The definition of Make/Break Timing is as follows;

RECOMMENDATIONS FOR ACTUAL DESIGN
* To assure proper electrical characteristics, use bypass capacitors with excellent high frequency characteristics for the power supply and keep them as close as possible to the device pins. * Connect the AG pin and the DG pin each other as close as possible. Connect to the system ground with low impedance. * Mount the device directly on the board when mounted on PCBs. Do not use IC sockets. If an IC socket is unavoidable, use the short lead type socket. * When mounted on a frame, use electro-magnetic shielding, if any electro-magnetic wave source such as power supply transformers surround the device. * Keep the voltage on the VDD pin not lower than -0.3 V even instantaneously to avoid latchup phenomenon when turning the power on. * Use a low noise (particularly, low level type of high frequency spike noise or pulse noise) power supply to avoid erroneous operation and the degradation of the characteristics of these devices. * Unused analog input pins must be connected to the VSG pin and unused digital pins must be connected to the GND pin.

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
