MAX3543 19-4985 Rev 2 7/10 Multiband Analog and Digital Television Tuner General Description Features The MAX3543 hybrid broadband single-conversion tele- S Standard IF Architecture Ensures < -70dBc Spurs vision tuner is designed for use in analog (PAL, SECAM) S Integrated RF Tracking Filter + digital (DVB-T, GB20600) television sets and terrestrial S Integrated IF Bandpass Filter receivers. It receives all television bands from 47MHz S Full-Band Coverage (47MHz to 862MHz) to 862MHz and converts the selected channel to an industry-standard 36MHz IF. S 70dB Image Rejection The MAX3543 includes a variable-gain low-noise input S 4dB Noise Figure amplifier an RF tracking filter an image rejection mixer S Fast-Locking, Low Phase-Noise PLL Supports a peak detector an optional internal, self-contained 256QAM RF gain-control loop (RFAGC) a VCO with fractional-N S Crystal Oscillator and Buffer/Divider to Drive PLL an IF bandpass filter an IF variable-gain amplifier Baseband IC separate analog and digital IF outputs and a crystal oscillator. S 745mW Power Dissipation The MAX3543 is available in a small, 6mm x 6mm, thin QFN package, and the application circuit fits in 20mm x 25mm on Ordering Information a two-layer board with single-sided component mounting.
