AHA4011

The AHA4011 is a member of the AHA family of high performance, single-chip, Reed-Solomon Forward Error Correction (FEC) devices. A single-phase clock synchronizes all chip functions. CMOS technology and custom design techniques help achieve the highest performance and density. The AHA4011 implements a standard polynomial approved by organizations such as Intelsat.
