DVB-T2/T/C/S/S2 Digital TV Demodulator
The Si2169B integrates DVB-T2, DVB-T, DVB-C, DVB-S, and
DVB-S2 digital demodulators into a single advanced CMOS
technology mixed-signal die for next generation terrestrial,
cable, and satellite TV standards. Leveraging Silicon Labs'
proven digital demodulation architecture, the Si2169B
achieves excellent reception performance for each media
while significantly minimizing front-end design complexity,
cost, and power dissipation. Connecting the Si2169B to a
terrestrial and cable hybrid TV tuner or digital only tuner, such
as Silicon Labs’ Si2178/58/48 devices, results in a
high-performance and cost optimized TV 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.
The DVB-T and DVB-C demodulators are enhanced versions
of proven and broadly used Si2167B/68/69 Silicon Labs
devices.
The satellite demodulation functionality allows demodulating
widely deployed DVB-S, DIRECTV™ (DSS) legacy
standards, and next generation DVB-S2 (AMC compliant)
satellite broadcasts. A zero-IF interface allows for a seamless
connection to market proven satellite silicon tuners. Constant
coding modulation (CCM), 64800 bits frame, and single TS
(broadcast profile) are the main specifications of the DVB-S2
demodulator.
The Si2169B offers an on-chip blind scanning algorithm for
DVB-S/S2 and DVB-C standards (as well as blind lock). It
also integrates DiSEqC™ 2.0 LNB interface for satellite dish
control and an equalizer to compensate for echoes in long
cable feeds from the LNB to the satellite tuner RF input.
The Si2169B programmable transport stream 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.
