Si2180-B60 Data Short

Si2180-B60
ISDB-T and DVB-T/C Demodulator
Description
The Si2180 integrates digital demodulators for the Japanese
and South American terrestrial ISDB-T standard and for the
DVB-T and DVB-C standards in a single advanced CMOS die.
Leveraging Silicon Labs' proven digital demodulation
architecture, the Si2180 achieves excellent reception
performance for each media while significantly minimizing
front-end design complexity, cost, and power dissipation.
Connecting the Si2180 to a hybrid TV tuner or digital only
tuner, such as Silicon Labs' Si217x/5x/4x devices, results in a
high-performance and cost optimized TV or STB front-end
solution.
Leveraging significant field experience in DVB terrestrial
demodulation (DVB-T), Silicon Labs’ internally-developed
ISDB-T demodulator can accept standard or low-IF inputs
(differential) and complies with the Brazilian SBTVD-T
terrestrial specifications (ABNT NBR 16.601 and 15.604).
Main features include fast channel scan, very short lock times,
state of the art CCI performance, partial reception, and
auxiliary channels decoding. DVB-T and DVB-C demodulators
are next-generation enhanced versions of proven and
broadly-used Silicon Labs’ Si2169/68/67/66/64/62/60 devices.
The cable reception allows demodulating widely deployed
DVB-C legacy standard (ITU J.83 Annex A/C) and the
Americas' cable standard (ITU J.83 Annex B).
The Si2180 offers an on-chip blind scan algorithm for DVB-C
standard, as well as a blind lock function. The Si2180
programmable transport stream output interface provides a
flexible range of output modes and is fully compatible with all
MPEG decoders or conditional access modules to support any
customer application.
