Multiband Analog and
Digital Television Tuner
General Description
The MAX3543 hybrid broadband single-conversion tele-
vision tuner is designed for use in analog (PAL, SECAM)
+ digital (DVB-T, 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 MAX3543 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;
separate analog and digital IF outputs; and a crystal
oscillator.
The MAX3543 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.
