Multiband Digital Television Tuner
General Description
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.
