MAXIM MAX3570/MAX3571/MAX3573 Manual
Update: 30 September, 2023
MAX3570/MAX3571/MAX3573 low-cost, wideband, dual-conversion tuner chips are designed for digital TV receivers. Each chip integrates all necessary RF functional modules, including an integrated HI-IF filter, a fully integrated VCO, and an IF VGA. The operating frequency ranges from 50MHz to 878MHz, while providing more than 60dB of RF and IF controllable gain range. MAX3570/MAX3571 have IF frequencies centered at 44MHz, while MAX3573 has IF output centered at 36MHz. All three chips include a variable-gain RF front end with a noise figure of only 8dB. A dual synthesizer produces two LO frequencies and provides excellent phase noise performance with phase noise of -86dBc/Hz at 10kHz offset. The integrated HI-IF filter has a 55dBc (typ.) image rejection. Only one IF SAW filter, passive loop filter and crystal oscillator are needed to build a complete single-chip tuner. MAX3570 chip programming and configuration are accomplished by a 3-wire serial interface, while MAX3571/MAX3573 chip programming and configuration are accomplished by a 2-wire serial interface. MAX3570/MAX3571/MAX3573 are packaged in a 48-pin QFN-EP package and are capable of operating in the commercial temperature range (0°C to +70°C).
