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.
