Si2166-B22 Data Short

Si2166-B22
DVB-S/S2 Satellite TV Demodulator
Description
Features
- 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 (optimized for 2 to 32 MSymbol/s)
- DIRECTV™ AMC compatible
- DVB-S (ETSI EN 300 421)
- QPSK demodulator and enhanced FEC decoder
- 1 to 45 MSymbol/s
- DIRECTV™ DSS supported
- DiSEqC™ 2.0 interface and Unicable support
- I2C serial bus interfaces (master and host)
- Two ADCs with differential inputs (ZIF input)
- GPIOs and multi-purpose ports for independent AGCs
The
Si2166-B22
integrates
DVB-S,
DVB-S2
(AMC-compliant), and DSS digital demodulators into a
single CMOS chip for the broadest range of satellite TV
standards. Leveraging Silicon Labs' proven digital
demodulation architecture, the Si2166-B22 achieves
superior satellite reception performance while minimizing
front-end design complexity and cost.
The
satellite
demodulation
functionality
allows
demodulating widely deployed DVB-S, DIRECTV™ (DSS)
legacy standards, and DVB-S2 satellite broadcast. A
zero-IF interface with two high-speed ADCs allows for a
seamless connection to market proven satellite silicon
tuners. 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.
-
For DVB-S/DSS standards, an innovative and advanced
FEC decoding scheme is implemented resulting in higher
performance.
The Si2166-B22 offers an on-chip blind scanning algorithm
for DVB-S and DVB-S2 standards (as well as blind lock
function). It also integrates DiSEqC™ 2.0 LNB interface for
satellite dish control.
