ISDB-T and DVB-T2/S2/S2X/T/C/S Demodulator
Description
The Si2182 integrates digital demodulators for the Japanese and
South American terrestrial ISDB-T standard and for all first and
second generation DVB standards (DVB-T2/T/C/S/S2 and S2X) in
a single advanced CMOS die. Leveraging Silicon Labs' proven
digital demodulation architecture, the Si2182 achieves excellent
reception performance for each media while significantly
minimizing front-end design complexity, cost, and power
dissipation. Connecting the Si2182 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-T2/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-T2/T,
DVB-S2/S
and
DVB-C
demodulators
are
next-generation enhanced versions of proven and broadly-used
Silicon Labs’ Si2169/68/67/66/64/62/60 devices. DVB-T2-Lite
(ETSI EN 302 755-V1.3.1) compatibility is also supported.
The satellite reception allows demodulating widespread DVB-S,
DIRECTV™ (DSS), DVB-S2, DIRECTV™ (AMC) legacy
standards, and new Part II of DVB-S2 (S2X) satellite broadcast
standard. A zero-IF interface (differential) allows for a seamless
connection to market proven satellite silicon tuners. Si2182
embeds DiSEqCTM 2.0 LNB interface for satellite dish control and
an equalizer to compensate for echoes in long cable feeds from
the antenna to the satellite tuner input.
The cable reception allows demodulating widely deployed DVB-C
legacy standard (ITU-T J.83 Annex A/C) and the Americas' cable
standard (ITU-T J.83 Annex B).
The Si2182 offers an on-chip blind scan algorithm for DVB-S/S2/
S2X and DVB-C/C2 standards, as well as a blind lock function.
The Si2182 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.
