Si21802-B60
The Si21802 integrates two separate high-performance digital
demodulators for the Japanese and South American terrestrial
ISDB-T standard and for the DVB-T and DVB-C standards in a
single compact package. Leveraging Silicon Labs' proven digital
demodulation architecture, the Si21802 achieves excellent
reception performance for each media while significantly
minimizing front-end design complexity, cost, and power
dissipation. Connecting the Si21802 to a dual terrestrial/cable TV
tuner results in a high-performance and cost optimized TV or STB
front-end solution.
Leveraging significant field experience in DVB terrestrial
demodulation (DVB-T), the Si21802 dual 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-T J.83 Annex A/C) and the Americas' cable
standard (ITU-T J.83 Annex B).
The Si21802 offers an on-chip blind scanning algorithm for DVB-C
standard, as well as blind lock function.
The Si21802 embeds two independent programmable transport
stream interfaces which provide a flexible range of output modes,
including a cross-bar functionality, and are fully compatible with all
MPEG decoders or conditional access modules to support any
customer application.
