Description

The Si2180 integrates digital demodulators for the Japanese

and South American terrestrial ISDB-T standard and for the

DVB-T and DVB-C standards in a single advanced CMOS die.

Leveraging Skyworks' proven digital demodulation

architecture, the Si2180 achieves excellent reception

performance for each media while significantly minimizing

front-end design complexity, cost, and power dissipation.

Connecting the Si2180 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-T), Skyworks’ internally-developed ISDBT

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-T and DVB-C demodulators

are next-generation enhanced versions of proven and broadlyused

Skyworks’ Si2169/68/67/66/64/62/60 devices.

The cable reception allows demodulating widely deployed

DVB-C legacy standard (ITU J.83 Annex A/C) and the

Americas' cable standard (ITU J.83 Annex B).

The Si2180 offers an on-chip blind scan algorithm for DVB-C

standard, as well as a blind lock function. The Si2180

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.
