10 / 48 page  10 L64733/L64734 Tuner and Satellite Receiver Chipset XTLOUT Crystal Out Output This signal provides a buffered clock reference frequency for driving the L64734 XOIN pin. Control Signals The following signals, some of which are generated by the L64734 IC, control the mode of operation of the L64733 IC. AGC1 Automatic Gain Control 1 Input The AGC1 signal is a high-impedance input from the L64734; it controls the RF AGC circuitry. The AGC1 voltage range is from 0.5 V to 4.8 V. AGC2 Automatic Gain Control 2 Input The AGC2 signal is a high-impedance input from the L64734; it controls RF AGC circuitry. CPG[2:1] Charge Pump Gain Input The CPG[2:1] signals set the charge pump gain according to the following table. FDOUB Frequency Doubler Input When the FDOUB signal is asserted, the L64733 local oscillator frequency is internally doubled and fed to the mixers. When the FDOUB signal is deasserted, the oscillator frequency is not doubled before being fed to the mixers. FLCLK Filter Clock Input The FLCLK signal is a low-amplitude, self-biased clock input. The frequency of the FLCLK signal multiplied by 16 is the baseband filter’s −3 dB frequency. IDCn, IDCp I-Channel DC Offset Correction Input Connect a 0.1 µF (or larger) capacitor between the IDCp and IDCn signals. Charge Pump Current (typ), mA CPG1 CPG2 FB HIGH FB LOW 0 0 0.1 −0.1 0 1 0.3 −0.3 1 0 0.6 −0.6 1 1 1.8 −1.8 |
