Description

The Si2169 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 Si2169

achieves excellent reception performance for each media

while significantly minimizing front-end design complexity,

cost, and power dissipation. Connecting the Si2169 to a

terrestrial and cable hybrid TV tuner or digital only tuner,

such as Silicon Labs’ Si2176/56/46 devices, results in a

high-performance and cost optimized TV front-end solution.

Silicon Labs internally developed DVB-T2 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

signalling 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 Si2161/63/65/67 Silicon Labs devices.

The satellite demodulation functionality allows demodulating

widely

standards, and next generation DVB-S2 and DIRECTV™

(AMC) 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 Si2169 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 Si2169 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.
