Fresco Microchip FM1050 Audio Video Demodulator

The FM1050, from Fresco Microchip, is an audio/video demodulator for cable and terrestrial broadcast television reception. The FM1050 supports NTSC, PAL, and SECAM analog broadcast standards. The FM1050 is available in a 40-pin 5×5 QFN package. Samples are available now to qualified customers. The chip is ideal for standard analog-only tuner modules or on-board platforms commonly found in TVs, set-top boxes, and DVD-Rs.

The FM1050 was developed to address the analog TV market. It is the first standalone universal legacy demodulator IC to eliminate the need for multiple external SAW filters typically required for TV-grade reception. The chip features Fresco’s iSAW technology, which delivers the industry’s best adjacent channel rejection and greatly simplifies traditional designs through significant component count and cost reduction.

The FM1050 accepts a standard 36MHz intermediate frequency (IF) signal from a silicon tuner or traditional MOPLL based CAN tuner and demodulates standard (NTSC/PAL/SECAM) and non-standard worldwide audio/video analog formats. The FM1050 also features Fresco’s smartTUNE technology for enhancing picture quality by reducing the visible effects of television interference caused by tuner artifacts.
