Si2169-D60
DVB-T2/T/C/S/S2/S2X Digital TV Demodulator
Description
The Si2169D integrates digital demodulators for 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 Si2169D achieves excellent
reception performance for each media while significantly
minimizing front-end design complexity, cost, and power
dissipation. Connecting the Si2169D 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.
Silicon Labs internally developed DVB-T2, including T2-Lite,
demodulator can accept a standard IF (36 MHz) or low-IF input
and support all modes specified by the DVB-T2 standard. Main
features of the DVB-T2 mode are 256 QAM with rotated
constellations, SISO and MISO support, FEF management, fully
autonomous signal acquisition including automatic L1 signaling
parsing, 600 kHz acquisition range, support for all pilot patterns,
and DVB-T2/T auto-detection.
DVB-T, DVB-C, and DVB-S2/S demodulators are next-generation
enhanced versions of proven and broadly-used Silicon Labs’
Si2169/68/67/66/64/62/60 devices.
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. Si2169D
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 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 Si2169D offers an on-chip blind scan algorithm for DVB-S/S2/
S2X and DVB-C standards, as well as a blind lock function. The
Si2169D 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.
