The MAX2851 is a single-chip, 5-channel RF receiver IC designed for 5GHz wireless HDMI™ applications. The IC includes all circuitry required to implement the complete 5-channel MIMO RF receiver function and crystal oscillator, providing a fully integrated receive path, VCO, frequency synthesis, and baseband/control interface.
The MAX2851 is a single‑chip, 5‑channel RF receiver IC designed for 5 GHz wireless HDMI (WHDI) applications. It integrates a sigma‑delta fractional‑N PLL, on‑chip VCO, crystal oscillator, and baseband interfaces, delivering a fully integrated receive path with programmable gain and filtering.
The device is supplied in a 68‑pin TQFN lead‑less package (10 mm × 10 mm) and operates from 2.7 V to 3.6 V across a temperature range of –25 °C to +85 °C. It supports 4‑wire SPI control, provides both in‑channel and RF RSSI, and includes on‑chip I/Q calibration and LO coherence across all channels.
