MAX3544:Multiband Digital Television Tuner

Achieves Highest Performance with Spur-Free, Easy Design-In Architecture Addressing Worldwide Digital Standards

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.
