L64733/L64734 Tuner and Satellite Receiver Chipset Datasheet The L64733/34 chipset is designed specifically to meet the needs of satellite broadcast digital TV and is compliant with the European digital video broadcast (DVB-S) standard and the technical specifications for DSS systems. The chipset forms a complete "L-Band to bits" system. A typical application of the L64733/34 chipset is satellite digital TV reception in accordance with ETS 300 421.

The L64733 handles a fully loaded raster of transponder signals from 925 MHz to 2175 MHz. RF In is internally matched to 75 , and except for a DC-blocking capacitor, requires no matching network between the cable connector and the L64733 input pins. The L64733 uses the L64734 INSEL signal to select the appropriate RF function (Normal or Loop-Through mode). The RF signal goes to a variable gain stage, which is controlled by the L64734 AGC1 signal. The L64734 adjusts AGC1 in conjunction with AGC2 to maximize the SNR of the RF signal while maintaining proper levels at the baseband outputs (IOUT and QOUT). The signal then goes to two mixers in the quadrature demodulator. The mixers are fed with local oscillator signals that are offset by 90 degrees from one another. The quadrature demodulator performs a direct frequency conversion of the RF signal to baseband while splitting the signal into quadrature I and Q signal paths. The baseband signals pass through a pair of variable-gain amplifiers that are controlled by the AGC2 pin, which, in turn is controlled by the L64734. The signals are then filtered through a pair of 7th-order filters for anti-aliasing. The filter shape is 7th-order Butterworth, followed by a single-pole delay equalizer. The filter cut-off frequency, which is controlled by the L64734 FLCLK signal, is related to the baud rate. The filtered baseband output signals go to the differential output stages at IOUTp, IOUTn, QOUTp and QOUTn. The baseband outputs of the L64733 go to the L64734, where they are digitized by the analog-to-digital converter (ADC). The outputs then go to a BPSK/QPSK demodulator, where they are filtered. The demodulator then sends them to the L64734 FEC decoder pipeline, which outputs an MPEG-2 transport stream. The frequency synthesizer functionality is split between the L64733 and L64734. The Synthesizer Control Module resides on the L64734; it generates control signals for the L64733 Tuner IC frequency synthesizer. The Synthesizer Control Module also contains some of the programmable counters that are part of the synthesizer feedback loop. The L64733 contains many of the analog functions of the frequency synthesizer, as well as the RF local oscillator and crystal reference oscillator. Tuning oscillator signals are generated for the mixers in the 4 L64733/L64734 Tuner and Satellite Receiver Chipset range from 925-2175 MHz, with a 0.5 MHz step size when using a 4-MHz crystal reference. The on-chip VCO tuning frequency is 543 MHz to 1088 MHz. To tune channels from 925-1086 MHz, the L64734 disables the frequency doubler (X2 block) on the L64733. To tune channels from 1086 MHz to 2175 MHz, the L64734 enables the frequency doubler. The VCO requires an external resonant tank circuit, which includes varactor diodes to vary the frequency of oscillation. The VCO signal goes to the Prescaler block before it is passed to the L64734 differentially through the PSOUTp and PSOUTn pins. The L64734 MODp and MODn differential signals control the divider ratio for the Prescaler block. The L64734 dynamically changes the divide ratio to ensure that the tuning step size is not affected by the divider. The L64734 contains programmable counters to further divide the signal in frequency before the signal is fed back to the L64733 through the PLLINp and PLLINn pins. The crystal reference oscillator frequency is divided by eight, then fed to the phase detector. The phase detector generates a current signal proportional to the difference in phase between PLLINp, PLLINn, and the divided crystal frequency. A charge pump circuit (which controls pins CP, FB) and an external transistor (to buffer the L64733 against the tuning voltage of 28 V) generate the current. The current is filtered, fed through a discrete loop filter, and converted to a tuning voltage that drives the external varactor diodes for the VCO tank circuit. A complete frequency controlled loop is formed, and the VCO frequency can be varied by changing the frequency divider ratios in the L64734 registers. See Figure 7 on page 22 for more details regarding the external circuitry for the VCO, crystal oscillator, charge pump, tank circuitry, and entire frequency-controlled loop. The chipset provides maximum integration and flexibility for system designers at a minimum cost. The number of external components required to build a system is minimal because the synthesizer, variable rate filters, and clock and carrier loops are all integrated into the two devices.

Channel Interface The Channel Interface is the input path to the L64734 satellite receiver. IVIN and QVIN are the I and Q streams, respectively, from the satellite tuner circuit. The CLK signal strobes in the data signals. IBYPASS[5:0] I Channel Data Input The IBYPASS[5:0] signals form the digital I channel data input bus, which supplies the I Stream to the L64734 when the ADC is bypassed. Bypass is controlled through the setting of particular register bits in the L64734. IVINn, IVINp I Channel Data Input These differential signals form the analog received I channel data input bus, which supplies the I stream to the L64734. QBYPASS[5:0] Q Channel Data Input The QBYPASS[5:0] signals form the digital received Q channel data input bus, which supplies the Q Stream to the L64734 when the ADC is bypassed. Bypass is controlled through the setting of particular register bits in the L64734. QVINn, QVINp Q Channel Data Input The QVINn and QVINp differential signals form the analog received Q channel data input bus, which supplies the Q stream to the L64734. 14 L64733/L64734 Tuner and Satellite Receiver Chipset Channel Clock Interface The Channel Clock Interface consists of the clock and crystal oscillator signals. CLK XOIN Input Clock Input This functionality has been assigned to the XOIN pin. Crystal Oscillator In Input The XOIN pin is used for a crystal oscillator or external reference clock input. A 15 MHz crystal is normally connected to the XOIN pin. This pin can also be driven by the XOOUT pin from L64733. When using an external ADC to strobe bypass data into the L64734, connect the clock input to this pin. Crystal Oscillator Out This is the crystal oscillator output pin. Output XOOUT Phase-Locked Loop (PLL) Interface The internal PLL generates the signals to operate the ADC, demodulator, and FEC modules. LCLK Decimated Clock Output Output The L64734 internal clock generation module generates the LCLK signal. LCLK is derived by dividing CLK by the value of the CLK_DIV2 register parameter. Input to VCO Input The LP2 signal is the input to the internal voltagecontrolled oscillator. It is normally connected to the output of an external RC filter circuit. PLL Clock Output Output The L64734 internal PLL clock synthesis module generates the PCLK signal. The PLL is driven by the reference crystal connected between the XOIN and XOOUT pins. The PLL clock synthesis module can be configured to generate a PCLK rate that is appropriate for all data rates. PLL Analog Ground Input PLLAGND is the analog ground pin for the PLL module; it is normally connected to the system ground plane. LP2 PCLK PLLAGND L64733/L64734 Tuner and Satellite Receiver Chipset 15 PLLVDD PLL Power Input PLLVDD is the power supply pin for the PLL module; it is normally connected to the system power (VDD) plane. PLL Ground Input PLLVSS is the ground pin for the PLL module; it is normally connected to the system ground plane. PLLVSS Control Signals Interface The Control Signals interface controls the operation of the L64734; it is not associated with any particular interface. IDDTn Test Input The IDDTn pin is an LSI Logic internal test pin. Tie the IDDTn pin LOW for normal operation. Reset Input This active-HIGH signal resets all internal data paths. Reset timing is asynchronous to the device clocks. Reset does not affect the configuration registers. Control Input Input The XCTR_IN pin is an external input control pin. It is sensed by reading the XCTR_IN register bit. Control Output/Sync Status Flag Output This signal indicates the synchronization status for one of three synchronization modules in the L64734 or the XCTR[3] field in Group 4, APR 55. The modules are the Viterbi decoder, Reed-Solomon deinterleaver (DI/RS), and descrambler. For any of the three synchronization outputs, asserting the XCTR[3] signal indicates that synchronization has been achieved for the sync module chosen using the SSS[1:0] register bits. When deasserted, the signal indicates an out-ofsynchronization condition. Control Output Output The XCTR[2:0] pins are external output control pins. They are set by programming particular register bits. XCTR[2] is mapped to CPG1, and XCTR[0] is multiplexed with CPG2, when used with the L64733 Tuner IC. When the on-chip serializer is used to generate a serial 2- or 3-wire protocol on the XCTR[2:0] pins, the mapping is XCTR[2] = EN, XCTR[1] = SCL, and XCTR[0] = SDA. RESET XCTR_IN XCTR[3] XCTR[2:0] 16 L64733/L64734 Tuner and Satellite Receiver Chipset Analog-to-Digital Converter (ADC) Interface The ADC module converts the incoming IVIN and QVIN signals into an internal 6-bit digital representation for processing.

AGC1, AGC2 Power Control Signals Output The AGC1 and AGC2 signals are the positive modulated output used for power control. These signals can each drive an external passive RC filter that feeds a gain control stage for dual-stage AGC. For a single-stage AGC, AGC1 can be used. L64733/L64734 Tuner and Satellite Receiver Chipset 17 Channel Data Output Interface The Channel Data Output interface is the output path from the L64734. It is typically connected to the input of the transport demultiplexer in a set-top decoder application. BCLKOUT Byte Clock Out Output This signal indicates valid data bytes on the CO[7:0] bus when the L64734 is in Parallel Channel Output mode. This signal cycles once every valid output data byte. It is used by the transport demultiplexer to latch output data from the L64734 at the BCLKOUT rate. Disregard the BCLKOUT signal when the L64734 is in Serial Channel Output mode. Channel Data Out Output The CO[7:0] signals form the decoded output data port. When the OF bit is 1 (Group 4, APR17), the L64734 operates in the Parallel Channel Output mode. In this mode, the L64734 outputs the channel data as eight-bitwide parallel data on the CO[7:0] signals. In Serial Channel Output mode (OF = 0), the L64734 outputs the channel data as serial data on CO[0]. The data is latched on every bit clock cycle. The chronological ordering in Serial Channel output mode is: MSB oldest, LSB newest. Channel Output Enable Input When asserted, the COEn signal enables the ERROROUTn, CO[7:0], DVALIDOUT, BCLKOUT, and FSTARTOUT signals. Operation of the receiver continues regardless of the state of the COEn signal. Valid Data Out Output The DVALIDOUT signal indicates that the CO[7:0] signals contain the corrected channel data. New data is valid on the CO[7:0] signals when the DVALIDOUT signal is asserted. DVALIDOUT is not asserted during the propagated check and GAP bytes. The DVALIDOUT signal is deasserted after the FEC_RST register bit (Group 4, APR 55) is set to 1. CO[7:0] COEn DVALIDOUT ERROROUTn Error Detection Flag Output The L64734 asserts the ERROROUTn signal at the beginning of any frame that contains an uncorrectable error; it deasserts ERROROUTn at the end of the frame 18 L64733/L64734 Tuner and Satellite Receiver Chipset if the error condition is removed. The ERROROUTn signal is exactly aligned with the output data stream; it is asserted after the FEC_RST register bit is set. FSTARTOUT Frame Start Output Output The L64734 asserts the FSTARTOUT signal during the first bit of every frame with valid data in Serial Channel output mode, and during the first byte in Parallel Channel output mode. FSTARTOUT is valid only when the DVALIDOUT signal is asserted. The FSTARTOUT signal is deasserted after the FEC_RST register bit is set. Microcontroller Interface The Microcontroller interface connects the L64734 to an external microcontroller. INTn Interrupt Output The L64734 asserts INTn when an internal, unmasked interrupt flag is set. The INTn signal remains asserted as long as the interrupt condition persists and the interrupt flag is not masked. Serial Address Input The SADR[1:0] signals are the two programmable bits of the serial address for the L64734. Serial Clock Bidirectional This is the serial clock pin for a two-wire serial protocol. Serial Data Bidirectional This is the serial data pin for a two-wire serial protocol. SADR[1:0] SCLK SDATA Synthesizer Control Interface The Synthesizer Control interface lets the L64734 control the L64733 frequency synthesizer. FDOUB Frequency Doubler Output When FDOUB is asserted, the frequency doubler on the L64733 Tuner IC is enabled. When FDOUB is deasserted, the frequency doubler is disabled. This output is set by register programming. L64733/L64734 Tuner and Satellite Receiver Chipset 19 MODn, MODp Modulus Selector Output These signals are low-voltage differential signals from the L64734 modulus selector programmable counter (A). The signals are clocked by PSOUT. A positive MODp with respect to MODn selects a divide by 32 at the dual modulus prescaler on the L64733 Tuner IC. A negative MODp with respect to MODn selects a divide by 33. Counter A can be programmed to count down from a particular value by register bit programming. PLLINn, PLLINp PLL Differential Counter M Output These signals are low-voltage differential signals from the L64734 programmable synthesizer counter (M). The signals are clocked by PSOUT. PLLINp is positive with respect to PLLINn for one PSOUT cycle. The repetition rate is 0.5 MHz for a 4 MHz reference crystal. The counter M can be programmed to count down from a particular value by register bit programming. PSOUTn, PSOUTp Prescaler Output Output These signals are differential signals to the L64734 from the L64733. The programmable counters on the L64734 are clocked on the rising edge of the PSOUT signal. RESO_LVDS LVDS Buffers Precision Resistor Output The RESO_LVDS output must be connected to a resistor (6.8 k 5%) that controls the swing of the LVDSOUT buffers used to drive the differential signals MODp, MODn, and PLLINp, PLLINn. Connect the other side of the resistor to ground. VREF_LVDS LVDS Buffers Reference Voltage Input The VREF_LVDS input is a 1.2 V 10% voltage level that controls the common mode voltage of the LVDSOUT buffers used to drive the differential signals MODp, MODn, and PLLINp, PLLINn. 20 L64733/L64734 Tuner and Satellite Receiver Chipset Tuner Control Interface The Tuner Control interface contains signals that control the L64733 Tuner IC. FLCLK Filter Control Clock Output FLCLK is the output of a programmable integer value divider clocked by the demodulator sampling clock, PCLK. The division ratio can be programmed with register bits. The frequency of FLCLK multiplied by 16 is the 3 dB cutoff of the programmable low-pass filters on the L64733. RF Input Select Output When INSEL is asserted, the L64733 tuner selects the normal mode. When INSEL is deasserted, the L64733 selects the Loop-Through mode.
