MAX3544 is a single-conversion television tuner produced by Maxim. It supports DVB-T, DVB-C, GB20600 standards, and receives frequencies from 47MHz to 862MHz. The output frequency is 36MHz IF.
The Maxim MAX3544 is a broadband single‑conversion tuner designed for digital television sets and terrestrial receivers. It covers the full TV band from 47 MHz to 862 MHz and converts the selected channel to a standard 36 MHz IF. The device integrates a low‑noise input amplifier, RF tracking filter, image‑rejection mixer, peak detector, optional RF‑AGC loop, fractional‑N PLL VCO, IF band‑pass filter, IF VGA, and a crystal oscillator, all in a 6 mm × 6 mm QFN package.
The datasheet provides absolute maximum ratings, DC and AC electrical characteristics, a complete pin description, I²C‑compatible serial interface details, typical register settings, and performance graphs such as gain, noise figure, and blocker handling. It also includes application guidance for selecting input ports and tracking filters based on frequency.
