| DATA SHEET CX74063-26: RF Transceiver for Multi-Band GSM, GPRS, and EDGE Applications with Power Ramping Controller and Integrated Crystal Oscillator with 26 MHz Output APPLICATIONS * GSM850, EGSM900, DCS1800, and PCS1900 handsets * GPRS handsets and modules * EDGE downlink support DESCRIPTION The CX74063-26 transceiver is a highly integrated device for multi-band Global System for Mobile CommunicationsTM (GSMTM) or General Packet Radio Service (GPRS) applications. The device requires a minimal number of external components to complete a GSM radio subsystem. The CX74063-26 supports GSM850, EGSM900, DCS1800, and PCS1900 applications. The receiver also supports downlink Enhanced Data-Rate GSM Evolution (EDGE). The receive path implements a direct down-conversion architecture that eliminates the need for Intermediate Frequency (IF) components. The CX74063-26 receiver consists of three integrated Low Noise Amplifiers (LNAs), a quadrature demodulator, tunable receiver baseband filters, and a DC-offset correction sequencer. In the transmit path, the device consists of an In-phase and Quadrature (I/Q) modulator within a frequency translation loop designed to perform frequency up-conversion with high output spectral purity. This loop also contains a phase-frequency detector, charge pump, mixer, programmable dividers, and high power transmit Voltage Controlled Oscillators (VCOs) with no external tank required. With the integrated gain controller (and an integrator ), the device realizes the Power Amplifier Control (PAC) functionality when combined with a coupler, a Radio Frequency (RF) detector and a Power Amplifier (PA). The CX74063-26 also features an integrated, fully programmable, sigma-delta fractional-N synthesizer suitable for GPRS multi-slot operation. Except for the loop filter, the frequency synthesizer function, including a wideband VCO, is completely on-chip. The reference frequency for the synthesizer is supplied by the integrated crystal oscillator circuitry. The 56-pin 8x8 RF Land Grid Array (RFLGATM) device package and pin configuration are shown in Figure 1. A functional block diagram is shown in Figure 2. Signal pin assignments, functional pin descriptions, and equivalent circuitry are provided in Table 1.

Includes three integrated LNAs, a quadrature demodulator section that performs direct down conversion, baseband amplifier circuitry with I/Q outputs, and three stages of DC offset correction. The receiver can be calibrated to optimize IP2 performance. * Synthesizer section. Includes an integrated on-chip VCO locked by a fractional-N synthesizer loop, and a crystal oscillator to supply the reference frequency. * Transmit section. The TX path is a translational loop architecture consisting of an I/Q modulator, integrated high power VCOs, offset mixer, programmable divider, PFD, and charge pump. The device also provides integrated gain controller for the PAC loop, plus the bias generator for an external diode detector. 8 MAY 16, 2003 A 3-wire serial interface controls the transceiver and synthesizer. The receiver gain control, as well as the division ratios and charge pump currents in the synthesizer and transmitter, can be programmed using 24-bit words. These 24-bit words are programmed using the 3-wire input signals CLK, DATA, and LE. Pin 43 (VDDBB) is provided for the digital sections to allow power supply operation compatible with modern digital baseband devices. VDDBB is also used to supply registers 0 through 5 to maintain programmed values. The TXENA, RXENA, and SXENA signals separately enable the CX74063-26 transmitter, receiver, and synthesizer sections. TXENA and RXENA should be held low during programming. SXENA should be held high during the programming of register 3 (IP2 calibration). (These timing signals are detailed in Figures 9, 10, and 11.) Skyworks Solutions, Inc., Proprietary and Confidential [781] 376-3000 I FAX [781] 376-3100 I SALES@SKYWORKSINC.COM I WWW.SKYWORKSINC.COM 103052A Data Sheet I CX74063-26 Receive Section LNA and Quadrature Demodulator Three separate LNAs are integrated to address different bands of operation. These LNAs have separate single-ended inputs, which are externally matched to 50 . The gain is switchable between high (i.e., 15 dB typical) and low (i.e., -5 dB GSM, -7 dB DCS, and -5 dB PCS typical) settings. The LNA outputs feed into a quadrature demodulator that downconverts the RF signals directly to baseband. Two external 470 pF capacitors are required at the demodulator output to suppress the out-ofband blockers. Baseband Section An off-chip capacitor and three fixed poles of on-chip, low pass filtering provide rejection of strong in- and out-of-band interferers. In addition, a tunable, four-pole gmC filter provides rejection of the adjacent channel blockers. Incorporated within the fixed-pole filters are two switchable gain stages of 18 dB and 12 dB gain steps, respectively. There is an additional programmable gain amplifier with a gain range from 0 to + 34 dB, selectable in 2 dB steps in the four-pole tunable filter. The final filter output feeds an amplifier with a gain range from 0 to 30 dB, selectable in 6 dB steps. There is an additional gain stage on the four-pole tunable filter output, the auxiliary gain stage, selectable at 0 dB or + 6 dB. The gain control ranges are shown in Figure 3. Recommended combinations of individual block gain settings are shown in Table 22 for GSM900, Table 23 for DCS1800, and Table 24 for PCS1900. For added baseband interface flexibility, the four-pole filter, its associated Variable Gain Amplifier (VGA), and DC offset correction loop can be bypassed and turned off for current savings. In Table 2 the typical locations of all eight receiver baseband poles are given. The final four poles are produced by the tunable gmC filter, as set by the external resistor (recommended value is 39.2 k, 1%) placed from pin 29 to ground. For these tunable poles, Table 2 gives the pole location as a function of this resistor. DC Offset Correction Three DC offset correction (DCOC) loops ensure that DC offsets, generated in the CX74063-26, do not overload the baseband chain at any point. After compensation, the correction voltages are held on capacitors for the duration of the receive slot(s). Internally, on-chip timing is provided to generate the track and hold (T_H) signals for the three correction loops. The timing diagram for the DC offset correction sequence with reference to the receive slot is shown in Figure 4. A rising edge on either the RXENA signal, selected via the serial interface, places the DC compensation circuitry in the track mode. The timing parameters for each of the three compensation loops, tt_H1, tt_H2, and tt_H3, and the time between compensation start and the LNA being turned on, tFEENA, are defined via an internal state machine. The state machine is preprogrammed with fixed default values, but may be readjusted via the serial interface. The timing parameters for the three compensation loops and the LNA power-up are each independently defined, relative to the compensation start. Therefore, they may be programmed to occur in any order, but the sequences shown in Figure 4 and Figure 5 are recommended. The device default timing is shown in Figure 5, with a total time of 60 s. Individual default timings are given in Table 17. For user-programmed timing, the total time may be set as short as approximately 10 s when FREF has a 13 MHz clock applied. However, the shortest recommended total time is approximately 30 s, since at the highest gain settings, the resulting DC may degrade as correction time is reduced. AM Suppression and IP2 Calibration For direct conversion GSM applications, it is imperative to have extremely low second-order distortion. Mathematically, second-order distortion of a constant tone generates a DCterm proportional to the square of the amplitude. A strong interfering amplitude-modulated (AM) signal is therefore demodulated by second-order distortion in the receiver front end, and generates an interfering baseband signal. Table 2.

DC Offset Correction Timing (LNA On During Part of the DC Offset Correction Sequence) A commonly used measure for receiver second-order distortion is the second-order intercept point, IP2. For example, to ensure that the unwanted baseband signals are 9 dB below the wanted signal required under the AM suppression test for type approval (see 3GPP TS 51.010-1), an input IP2 of 43 dBm is required: The CX74063-26 receiver includes a circuit that minimizes second-order distortion. This IP2 calibration circuit effectively compensates any second-order distortion in the receive chain that would otherwise generate unwanted baseband signals in the presence of strong interfering signals. When calibrated correctly, the CX74063-26 IP2 meets the GSM AM suppression test requirements in all bands with good margin. To calibrate IP2, apply a strong RF signal at the receiver input and observe the resulting DC voltage level change at the receiver I/Q outputs. The exact frequency and level of the signal applied for the purpose of the calibration are not critical. The signal should, however, be within the receive band, but at least 6 MHz offset from the frequency to which the receiver is tuned. The level should be high enough tocause a notable DC shift at the I/Q outputs. A recommended value is -30 dBm at the LNA input, which applies to all three LNAs. A set of I/Q compensation coefficients can then be programmed to the device to minimize the DC voltage shift resulting from the second-order distortion. When the DC due to the interfering signal is minimized, the IP2 performance is optimized. The IP2 calibration is a one-time factory calibration that should be done for each band and each individual device for optimum performance. The determined coefficients must be stored in nonvolatile memory and programmed to the CX74063-26 upon each power-up as part of device initialization. There are onchip registers that must be programmed through register 3 with the appropriate IP2 coefficients for the band in use. As long as a supply voltage is maintained on pin 43, VDDBB, the IP2 coefficients for ILowband, IHighband, QLowband, QHighband, programmed to the device remain in the registers. After the supply voltage has been removed from VDDBB, the coefficients must be re-programmed to the device again. Synthesizer Section The CX74063-26 includes a fully integrated UHF VCO with an on-chip LC tank. A single sigma-delta fractional-N synthesizer can phase-lock the local oscillator used in both transmit and receive paths to a precision frequency reference input. Fractional-N operation offers low phase noise and fast settling times, allowing for multiple slot applications such as GPRS. The CX74063-26 frequency stepping function with a 3 Hz resolution allows triple band operation in both transmit and receive bands using a fully integrated single integrated on-chip UHF VCO. The fine synthesizer resolution allows direct compensation or adjustment for reference frequency errors. The fractional-N synthesizer consists of the following: * * * * * VCO High frequency prescaler N-divider with a sigma-delta modulator Reference buffer and divider Fast phase frequency detector and charge pump 11 MAY 16, 2003 Note: SXENA, pin 38, must be held high, and a clock signal must be present on XTAL, pin 34, during the programming of the IP2 calibration coefficients in register 3, see Table 18.

Digital Frequency Centering The CX74063-26 uses a novel technique whereby the UHF VCO frequency range is re-centered each time the synthesizer is programmed. This technique is called Digital Frequency Centering (DFC). The DFC technique: * Extends the VCO frequency coverage * Speeds up settling time * Ensures robust performance since the VCO is always operated at the center of its tuning range. Each time the synthesizer is programmed, the DFC circuit is activated, and the VCO is centered to the programmed frequency in less than 20 s. After this, normal Phase Locked Loop (PLL) operation is resumed and the fine settling of the frequency is finalized. The DFC typically adjusts the VCO center frequency to within a few MHz and no more than 5 MHz offset, and presets the tuning voltage to the center of the range before the PLL takes over. This speeds up frequency settling and ensures that the PLL control voltage never operates close to the rails. f VCO where: fVCO N FN R fREF = Generated VCO frequency = N-divider ratio integer part = Fractional setting = R-divider ratio = Reference frequency UHF VCO Frequency Setting For the receiver, to tune the receive frequency, fRX, set the VCO frequency, fVCO, as follows: * f VCO = * f VCO 3 f RX for GSM850/900 2 3 = f RX for DCS1800 and PCS1900 4 Phase Detect Ext Loop Filter fTx Tx VCO D2 Ext Tx I + D1 L/C Filter 900 Tx Q X2 where: fTx = fLO (2 D1 - D2)/D1 GSM:fLO = (fVCO)/3 DCS/PCS: fLO = (2fVCO)/3 X2 Fractional-N PLL UHF VCO fVCO /3 101514D 6_071101 Figure 6. Transmitter Frequency Generation 12 MAY 16, 2003 Skyworks Solutions, Inc., Proprietary and Confidential [781] 376-3000 I FAX [781] 376-3100 I SALES@SKYWORKSINC.COM I WWW.SKYWORKSINC.COM 103052A Data Sheet I CX74063-26 The DFC is an adaptive circuit that corrects for any VCO center frequency errors caused by variations of the integrated VCO circuit, temperature, supply voltage, aging etc. The VCO can be centered at any frequency in the range from 1.2 GHz to 1.55 GHz. Once centered, the VCO has a minimum analog tuning range of 30 MHz. No calibration or data storage is needed for DFC operation. It is activated by one of two events: * When the synthesizer is programmed, the rising edge of the LE signal starts the DFC cycle and, * When changing the level of the SXENA signal from low to high, thereby turning on the synthesizer, the rising edge of the SXENA signal starts the DFC cycle. Crystal Oscillator A crystal oscillator is designed to provide the reference frequency for the synthesizer. As shown in Figure 7, the oscillator uses an external crystal to generate an accurate oscillation frequency. The reference frequency can be changed through coarse tuning with an integrated capacitor array or fine tuning with the integrated varactor diode. The coarse tuning is done by switching in and out (using a digital word programmed via the serial interface) the capacitor network (CAP_A and CAP_B) located at the input of the integrated buffer. The fine tuning is done by providing a tuning voltage to the integrated varactor diode. Table 20 describes the control bits. An output buffer is provided to drive the baseband circuitry (XTALBUF, pin 30). The VCXO and buffer circuitry are powered from pin 33 (VCCF). When VCCF is ramped to a voltage greater than 2.6 V, the output buffer powers on. The oscillator core powers up when pin 4 (VCXO_EN) is set to logic 1. If pin 4 is tied permanently to logic 1, the R6 VCXO Control Register is set to a defined state by a power-on reset. Pin 4 should be held low if an external reference oscillator is used. The buffer may be disabled by programming bit 3 in the SX1 Control Register (see Table 13) to logic 0. Transmit VCOs Two on-chip transmit VCOs are designed to meet GSM850, EGSM900, DCS1800, and PCS1900 requirements. The transmit VCOs use the same DFC technique as described in the Synthesizer section to lock the translational loop. The rising edge on TXENA initializes the transmit DFC. Power Amplifier Gain Controller The device contains an error amplifier/integrator to provide transmit burst control for an external power amplifier (PA). As shown in Figure 8, when the device is connected to a PA, an RF detector, and a coupler, a loop is formed that controls the transmit power in a multi-band wireless application. The error amplifier amplifies and integrates the voltage difference between the RF detector output (PDET) and the power control input (BBVAPC). The output of the integrator is fed to an internal gain shaper that drives the gain control input (PAVAPC) of the external RF PA. The device. provides a bandgap voltage (PDETVCC) which can be used as the supply voltage for the external peak detector and can source up to 200 A. The PA pre-bias is activated after a programmable delay and time-referenced from the rising edge of TXENA. The time delay is set using the serial interface. See Table 19 for details. Digital Interface The transceiver and synthesizer are controlled by a single three-wire serial interface. The transmitter, receiver, and synthesizer are each enabled through external inputs according to typical timing requirements as shown in Figures 10 and 11. Band selection for the CX74063-26 is through the three-wire serial interface. The PCO signal (pin 3) provides a band selection control output. DC offset calibration and front-end activation timing can also be controlled by an on-chip signal sequencer, precluding the need for separate control signals. All the logic and the three-wire interface inputs are referenced to the PCO signal (pin 3). The RX/TX Control Register is used to program the transceiver and to preset other test word states by setting bit 22 as a logic 1. If any test words are to be altered from their preset states, bit 22 must be sent to the RX/TX Control Register again as a logic 0. Typically, this is done only on power-up since the device has a zero-power standby mode that retains programmed test memory. There are seven additional registers used to program various functions of the CX74063-26. The SX1 Control Register is used to program the fractional-N synthesizer and the SX2 Fractional-N Modulo Register is used to program the modulus. Three auxiliary registers are used to program the transceiver besides the RX/TX Control Register, and two 24-bit registers are used to program the synthesizer: * * * * SX1 Control SX2 Fractional-N Modulo RX/TX Control R0 Auxiliary Control 13 MAY 16, 2003 Transmit Section To minimize the post-PA filtering requirements and any additional post-PA losses, the transmit path consists of a vector modulator within a frequency translation loop. The translation loop consists of the following: * * * * * Phase Frequency Detector (PFD) and charge pump Mixer with an operating range of 800 MHz to 2 GHz An in-loop modulator Two programmable dividers Two transmit VCOs Translational Loop The translational loop takes baseband analog I/Q signals and modulates them with the mixed product of transmitter output and LO signal, as shown in Figure 6. The unmodulated result is compared with a divided down LO at the PFD and the difference is used to control the transmit VCO.

An algorithm using a test tone needs to be used to determine the coefficient for each individual part. R4 PAC Timing Control Register. This register is used to set timing for the PAC pedestal. See Table 19. R6 and R7 VCXO Control Registers. These registers are used to control the tuning range and oscillation frequency of the VCXO. See Tables 20 and 21, respectively. SX1 Control Register. This register is used to program the fractional-N synthesizer, and set the values of the integral-N divider and the input-R divider. The polarity of the Phase/Frequency Detector (PFD) may also be defined by this register. Refer to Table 13. SX2 Fractional-N Modulo Register. This register is used to program the 24-bit modulo of the fractional-N synthesizer. The data is a 22-bit binary coded decimal word that allows the PLL to lock to precise frequencies. Refer to Table 14. RX/TX Control Register. This register is used to control divide ratios and charge pump currents in the transmitter, and to control gain in the receiver along with the band select function. Refer to Table 15. R0 Auxiliary Control Register. This register is used to bypass the DC offset correction loops and the baseband filters. It also enables and disables the two on-chip transmit VCOs and defines the directionality of the LO port, which allows an external VCO or LO reference to be used or enables the internal VCO to be monitored. Refer to Table 16. R2 DC Offset Timing Register. This register sets the timing of the tracking of the three DC offset cancellation loops and the time at which the front end turns on relative to the RXENA signal (pin 1). It allows the front-end to be enabled using the internal timer. Refer to Table 17. R3 IP2 Calibration Register. This register is used to perform 2nd order Intercept Point (IP2) calibration by manually adjusting calibration coefficients. A total of four words need to be set: IP2 coefficients for I-high band, I-low band, Q-high band, and Q-low band. Refer to Table 18.
