AHA4012

The AHA4012 is the lowest cost member of the AHA PerFEC 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. Input and output rate flexibility, low processing latency and various programmable parameters make this an ideal part for many systems requiring Forward Error Correction.
