Description

The Si2167-B22 integrates DVB-T, DVB-C, DVB-S, DVBS2

(AMC-compliant), and DSS digital demodulators into a

single CMOS chip for terrestrial, cable, and satellite TV

standards. Leveraging Skyworks' proven digital

demodulation architecture, the Si2167-B22 achieves

superior reception performance for each media while

minimizing front-end design complexity and cost.

Connecting the Si2167-B22 to a terrestrial and cable hybrid

TV tuner, such as Skyworks’ Si217x, results in a high

performance and cost optimized TV front-end solution.

DVB-T and DVB-C demodulators are enhanced versions of

proven and broadly used Si2169/68/67-A Skyworks

devices. Furthermore, ITU J.83 Annex B is also supported

for US and South American cable networks. The IF input

supports standard IF (36 MHz) or low-IF.

For DVB-T and DVB-S/DSS, an innovative and advanced

FEC decoding scheme is implemented resulting in higher

performance.

The satellite demodulation functionality allows

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

legacy standards, and DVB-S2 satellite broadcast. A zero-

IF interface 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. Skyworks' innovative LDPC and BCH

decoding architecture delivers best-in-class reception while

exhibiting low power dissipation.

The Si2167-B22 offers an on-chip blind scanning algorithm

for DVB-S/S2 and DVB-C standards (as well as blind lock

function). It also integrates DiSEqC™ 2.0 LNB interface for

satellite dish control.

The Si2167-B22 programmable Transport Stream 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. Si2167-B22

is fully API compatible with Si2164/69/68/66.
