DVB-S2 Demodulator and Forward Error
Correction Decoder
CX24116
Conexant’s portfolio includes a comprehensive suite of semiconductor
solutions for broadband communications, enterprise networks, and the
digital home. The CX24116 is based on an open DVB-S2 standard and
offers an alternate path for service providers to use advanced modulation
(8PSK) with LDPC/BCH FEC. This will realize increased satellite throughput
that can be used to offer additional programming and services.
The CX24116 can demodulate and decode signals transmitted in
accordance with the new DVB-S2, DVB-S and DIRECTV specifications.
It has an automatic acquisition algorithm that searches and acquires the
carrier within a ±10 MHz range during initial acquisition and performs
a smart search to reacquire under fade condition. The CX24116 has an
on-chip microcontroller for fast-signal acquisition, Es/No estimation, and
system monitoring. In addition, the on-chip microcontroller saves software
integration time by minimizing the external driver code. The CX24116 has
integrated signal-to-noise ratio (SNR) and bit error rate (BER) monitors for
channel-performance measurements that simplify production testing.
The CX24116 can be used in conjunction with the Conexant’s CX24118 Tuner
w RF IC to create a complete satellite AMC front-end solution.
wwConexant’s advanced modulation front-end solution enables satellite STB
.Dproviders to deliver cost-effective, digital STBs that support a wide range of
consumer video services, such as transmitting additional local channels and
ataSheet4U.comhigh-definition television (HDTV) channels.
