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.

Eleven FCC Scenarios for The 600 MHz Band Plan
I suspect that the estimated $44 billion of auction proceeds do not take into account the fact that some spectrum the FCC will buy cannot be resold because it must be used as guard intervals in the 600 MHz band plan.~ Charles W. Rhodes
