1 / 2 page Worldwide TV Tuner Copyright © 2011 by Silicon Laboratories 9.20.11 Si2156 Worldwide High-Performance TV Tuner IC for Analog and Digital Standards Description The Si2156 integrates a complete hybrid TV tuner supporting all worldwide terrestrial and cable TV standards. Leveraging Silicon Labs’ field proven digital low-IF architecture, the Si2156 maintains the unmatched performance and design simplicity of the Si2153 while further reducing footprint size and bill of materials cost. No external LNAs, tracking filters, wirewound inductors, or SAW filters are used. Compared with competing silicon tuners and discrete MOPLL-based tuners, the Si2156 delivers superior picture quality and a higher number of received stations in crowded and near/far real-world reception conditions. The high linearity and low noise RF front-end delivers superior blocking performance and higher sensitivity in the presence of strong undesired channels and interference. The Si2156 integrates the complete signal path from antenna input to IF outputs for both analog and digital transmission standards. Compared to traditional discrete MOPLL-based tuners, the Si2156 eliminates hundreds of external components including external LNAs, tracking filter varactors and inductors (unlike competing silicon tuners), and SAW filters, resulting in the simplest, lowest-cost BOM for a hybrid TV tuner. I nterfacing the Si2156 seamlessly with the Si2165 DVB-T/C demodulator creates a complete terrestrial and cable DVB-T/C receiver plus PAL/SECAM tuner.
