Conexant introduces DVB-S2 demodulator and FEC decoder
Conexant Systems has unveiled the CX24116, a satellite set-top box (STB) demodulator and forward error correction (FEC) decoder based on the DVB-S2 standard.
The CX24116 advanced modulation front-end solution enables operators to offer additional content and services, such HDTV channels and interactive services, and basic local programming using existing bandwidth and infrastructure.
The STB offers a path for service providers to use advanced modulation with new low-density parity check (LDPC) and Bose-Chaudhuri-Hocquenghem (BCH) FEC.
It has an on-chip microcontroller for fast-signal acquisition, Es/No estimation and system monitoring. The fast-signal acquisition algorithm searches and acquires the carrier within a +/-10 MHz range during initial acquisition and performs a smart search to reacquire under fade conditions.
