Si2136
Worldwide Analog TV Tuner IC with Analog Demodulator
Description
The Si2136 integrates a complete analog tuner with
analog TV demodulator supporting all worldwide
terrestrial and cable ATV standards. Leveraging
Silicon Labs’ field proven digital low-IF architecture,
the Si2136 incorporates the unmatched performance
and design simplicity of the Si2173 into a platform
optimized for analog-only reception, 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 Si2136 delivers a higher
number of received stations in crowded and near/far
real-world reception conditions. The Si2136
incorporates Silicon Labs' third generation analog
demodulator, which delivers superior picture quality
and tolerance to a wide range of transmitter
performance
variations
and
overmodulation
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 Si2136 integrates the complete signal path from
antenna input to analog video and sound outputs.
Compared to traditional discrete MOPLL-based
tuners, the Si2136 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 an analog TV receiver while
improving performance in difficult reception
conditions.
