AHA4013B

The AHA4013B is a single chip integrated circuit that implements a high speed Reed-Solomon Forward Error Correction algorithm. The AHA4013B is a member of the AHA PerFEC^TM family of high speed forward error correction (FEC) devices conforming to the Intelsat IESS-308 specification.The device supports several programmable parameters, including, block size, error threshold,number of check bytes, order of output and mode of operations. Shortened blocks are supported without requirement of zero padding typically required in Reed-Solomon decoders. The data input port is used to initialize the programmable parameters and the two on-chip buffers are used to input and output data. Discontinuities in data flow may be controlled by dedicated control pins.

High operating frequency, input and output data rate flexibility, low processing latency and various programmable parameters make AHA4013B ideal for many applications including: DTV, DBS,ADSL, Satellite Communications, ISDN, High Performance Modems and networks.This specification provides full electrical and mechanical information to help a system engineer develop a system using AHA4013B. This document contains descriptions on correction terms, pinout,functions and features, DC and AC characteristics, package and mechanical specifications, ordering information and Related Technical Publications.Software simulation of the RS code as implemented in the AHA4013B is also available.
