Si21662-B22

Dual DVB-S/S2 Digital TV Demodulator

Description

Features

The Si21662-B integrates two separate high performance

DVB-S, DVB-S2 and DSS digital demodulators into a single

compact package for satellite TV standards. Leveraging

Silicon Labs' proven digital demodulation architecture, each

embedded demodulator achieves excellent reception

performance for each standard while significantly minimizing

front-end design complexity and cost. Connecting the

- DVB-S2 (ETSI EN 302 307 and TR102-376)

QPSK/8PSK demodulator and FEC decoder

Broadcast profile CCM, 64800 bits frame, single TS

1 to 45 MSymbol/s

DIRECTV AMC compatible

- DVB-S (ETSI EN 300 421) and DSS supported

- QPSK demodulator and enhanced FEC decoder

- 1 to 45 MSymbol/s

Si21662-B to

dual satellite tuner, results in

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

- Dual DiSEqC™ 2.x interface, Unicable support

The satellite demodulation functionality allows demodulating

widely deployed DVB-S, DIRECTV™ (DSS) legacy

standards, and DVB-S2 (AMC compliant) satellite broadcasts.

A zero-IF interface allows for a seamless connection to

market proven satellite silicon tuners.

- I C serial bus interfaces (master and host)

- Dual independent differential ZIF I/Q inputs

- GPIOs and multi-purpose ports (two per demodulator)

- Firmware control for upgradeability

- Separate flexible TS interfaces with serial or parallel 

outputs

Constant

Coding

Modulation

(CCM),

QPSK/8PSK

demodulation schemes and broadcast profile are the main

specifications of the DVB-S2 demodulator. Silicon Labs'

innovative LDPC and BCH decoding architecture delivers

best-in-class reception while exhibiting low power dissipation.

The Si21662-B offers an on-chip blind scanning algorithm for

DVB-S/S2 standards. It also integrates two DiSEqC™ 2.0

LNB interfaces for satellite dish control and, for each satellite

demodulator, an equalizer to compensate for echoes in long

cable feeds from the LNB to the satellite tuner RF input.

The Si21662-B embeds two independent programmable

transport stream interfaces which provide a flexible range of

output modes and are fully compatible with all MPEG

decoders or conditional access modules to support any

customer application.

- Fast lock times for all standards

- Only two power supplies: 1.2 and 3.3 V

- 8x8 mm, QFN-68 pin package, Pb-free/RoHS compliant

- Pin-to-pin compatible with all dual demodulator family:

Si216x2

- API compatible with all single and dual demodulator 

families

Applications

- Multi-receiver iDTV: on-board or in a NIM

- Advanced multimedia PVR STBs

- PC-TV accessories

- PVR, DVD, and Blu-Ray disc recorders
