TV tuner supports worlwide standards

Supporting all worldwide terrestrial and cable TV standards, the Si2155 silicon TV tuner IC is optimized for the cost/performance requirements of mainstream TVs. It is based on the company’s TV tuner architecture, which delivers clear TV reception for both analog (NTSC, PAL/SECAM) and digital (ATSC/QAM, DVB-T/T2/C, ISDB-T/C,DTMB) broadcasts.

Compared to traditional discrete MOPLL-based tuner solutions, designs based on the Si2155 eliminate more than 100 external components including LNAs, tracking filter inductors (unlike other silicon tuners) and SAW filters. No alighment, tuning or calibration is required. Housed in a 5 x 5-mm 32-pin QFN package, the part features a frequency range from 42 to 870 MHz and 3.3- and 1.8-V power supplies. ($1.23 ea/10,000; Si2176-B-EVB/Si2156-B-EVB, $495 — available now.)
