The MAX3543 hybrid broadband single-conversion television 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.

Applications

  • ATSC + NTSC
  • DTMB/GB20600 + PAL
  • DVB-C + PAL/SECAM
  • DVB-T/DVB-T2 + PAL/SECAM
