Description

The Si2168D integrates digital demodulators for first and second

generation DVB standards (DVB-T2/T/C) in a single advanced

CMOS die. Leveraging Skyworks' proven digital demodulation

architecture, the Si2168D achieves excellent reception

performance for each media while significantly minimizing frontend

design complexity, cost, and power dissipation. Connecting

the Si2168D 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.

Skyworks 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.

DVB-T and DVB-C demodulators are next-generation enhanced

versions of proven and broadly-used Skyworks’

Si2169/68/67/64/62/60 devices.

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 Si2168D offers an on-chip blind scan algorithm for the DVB-C

standard, as well as a blind lock function. The Si2168D

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.
