MAX3544

Multiband Digital Television Tuner

The MAX3544 broadband single-conversion television tuner is designed for use in digital DVB-T, DVB-C, GB20600 television sets and terrestrial receivers. It receives all television bands from 47MHz to 862MHz and converts the selected channel to an industry-standard 36MHz IF.

The MAX3544 includes a variable-gain low-noise input amplifier an RF tracking filter an image rejection mixer a peak detector an optional internal, self-contained RF gain-control loop RFAGC a VCO with fractional-N PLL an IF bandpass filter an IF variable-gain amplifier and a crystal oscillator.

The MAX3544 is available in a small, 6mm x 6mm, thin QFN package, and the application circuit fits in 20mm x 25mm on a two-layer board with single-sided component mounting.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
