Description

The Si2182 integrates digital demodulators for the Japanese and

South American terrestrial ISDB-T standard and for all first and

second generation DVB standards (DVB-T2/T/C/S/S2 and S2X) in

a single advanced CMOS die. Leveraging Skyworks' proven digital

demodulation architecture, the Si2182 achieves excellent

reception performance for each media while significantly

minimizing front-end design complexity, cost, and power

dissipation. Connecting the Si2182 to a hybrid TV tuner or digital

only tuner, such as Skyworks' Si217x/5x/4x devices, results in a

high-performance and cost optimized TV or STB front-end

solution.

Leveraging significant field experience in DVB terrestrial

demodulation (DVB-T2/T), Skyworks’ internally-developed ISDB-T

demodulator can accept standard or low-IF inputs (differential) and

complies with the Brazilian SBTVD-T terrestrial specifications

(ABNT NBR 16.601 and 15.604). Main features include fast

channel scan, very short lock times, state of the art CCI

performance, partial reception, and auxiliary channels decoding.

DVB-T2/T, DVB-S2/S and DVB-C demodulators are nextgeneration

enhanced versions of proven and broadly-used

Skyworks’ Si2169/68/67/66/64/62/60 devices. DVB-T2-Lite (ETSI

EN 302 755-V1.3.1) compatibility is also supported.

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. Si2182

embeds DiSEqCTM 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 Si2182 offers an on-chip blind scan algorithm for DVBS/

S2/S2X and DVB-C/C2 standards, as well as a blind lock

function. The Si2182 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.
