Integrated silicon tuner eases manufacturing

Housed in a 48-pin QFN package, the Si2170 globally compliant hybrid TV tuner with analog TV demodulator eliminates over 100 discrete components including the tracking-filter function, while avoiding costly manual inductor tuning/alignment. The tuner integrates a highly linear RF front-end design incorporating a merged LNA and high-Q tracking filter to provide gain only around the desired channel frequency.

The part offers a noised figure of 4 dB (about 2 dB better than discrete tuners) and a 4.5-dB margin to ATSC A/74 spec (average across frequency). The tuner is based on the company’s digital low-IF architecture. (From $3.95 ea/10,000 — available now.)
