Hi-if Single-chip Broadband Tuners

The MAX3570 MAX3571 MAX3573 low-cost, broad- band, dual-conversion Tuner ICs are designed for use in digital Television receivers. Each IC integrates all necessary RF functions, including an integrated HI-IF Filter fully integrated VCOs and an integrated IF VGA. The operating frequency range extends from 50MHz to 878MHz while providing over 60dB RF/IF gain-control range. The MAX3570 MAX3571 have an IF frequency centered at 44MHz, while the MAX3573 has an IF out- put centered at 36MHz. These devices include a variable-gain front-end, achiev- ing an overall 8dB noise figure. A dual synthesizer gen- erates both local Oscillator (LO) frequencies, providing superior phase noise performance of -86dBc/Hz at 10kHz. The integrated HI-IF Filter achieves 55dBc (typ) of image rejection. Only an IF SAW Filter passive loop fil- ters, and a crystal are needed to complete a single-chip Tuner Device programming and configuration are accomplished with a 3-wire serial Interface for the MAX3570 and with a 2-wire serial Interface for the MAX3571 MAX3573. The MAX3570 MAX3571 MAX3573 are available in a 48-pin QFN-EP package and are specified for the com- mercial (0C to +70C) temperature range. By Maxim Integrated Products
