Si2166-D60
DVB-S/S2/S2X Digital TV Demodulator
Description
The Si2166D integrates digital demodulators for first and second
generation satellite DVB standards (DVB-S/S2 and S2X) in a
single advanced CMOS die. Leveraging Silicon Labs' proven
digital demodulation architecture, the Si2166D achieves excellent
satellite reception performance while significantly minimizing
front-end design complexity, cost, and power dissipation.
Connecting the Si2166D to a satellite silicon tuner results in a
high-performance and cost optimized TV or STB front-end
solution.
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. Si2166D
embeds DiSEqC
TM
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 Si2166D offers an on-chip blind scan algorithm for DVB-S/S2/
S2X standards, as well as a blind lock function. The Si2166D
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.
