CX24116 DVB-S2 Demodulator and Forward Error Correction Decoder
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 SNR and BER monitors for channel-performance measurements that simplify production testing.
