Si2168-D60
DVB-T2/T/C Digital TV Demodulator
Description
Features
The Si2168D integrates digital demodulators for first and second
generation DVB standards (DVB-T2/T/C) in a single advanced
CMOS die. Leveraging Silicon Labs' proven digital demodulation
architecture, the Si2168D achieves excellent reception
performance for each media while significantly minimizing
front-end design complexity, cost, and power dissipation.
Connecting the Si2168D to a hybrid TV tuner or digital only tuner,
such as Silicon Labs' Si217x/5x/4x devices, results in a
high-performance and cost optimized TV or STB front-end
solution.
- Pin-to-pin compatible with all Si216x/8x single demods family
- API compatible with all single and dual demods families
- DVB-T2 (ETSI EN 302 755-V1.4.1) with T2-Lite (Annex I)
- Bandwidth: 1.7, 5, 6, 7, and 8 MHz (and extended BW)
- NorDig Unified 2.5 and D-Book 8 compliant
- DVB-T (ETSI EN 300 744)
- OFDM demodulator and enhanced FEC decoder
- NorDig Unified 2.5 and D-Book 8 compliant
- DVB-C (ETSI EN 300 429) and ITU-T J.83 Annex A/B/C
- QAM demodulator and FEC decoder
- 1 to 7.2 MSymbol/s
- I2C serial bus interfaces (master and host)
- Firmware control (embedded ROM/NVM)
- Upgradeable with patch download via I2C or fast SPI
- Flexible TS output interface (serial, parallel, and slave)
- Fast lock times for all media
- Low power consumption
- Two power supplies: 1.2 and 3.3 V
- 7x7 mm, QFN-48 pin package, Pb-free/RoHS compliant
DVB-T and DVB-C demodulators are next-generation enhanced
versions of proven and broadly-used Silicon Labs’ 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.

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.
