The MAX2852 is a single-chip RF receiver IC designed for 5GHz wireless HDMI applications. The IC includes all circuitry required to implement the complete receiver function and crystal oscillator, providing a fully integrated transmit path, VCO, frequency synthesis, and baseband/ control interface. It includes a fast-settling, sigma-delta RF fractional synthesizer with 76Hz frequency programming step size. The IC also integrates on-chip I/Q amplitude and phase-error calibration circuits. The receiver includes both an in-channel RSSI and an RF RSSI. The receiver chip is housed in a small, 68-pin thin QFN leadless plastic package with exposed pad.
