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.
