AHA4210 General Description

The AHA4210, referred to as the RSVP, is a single-chip Forward Error Correction LSI device combining a Viterbi decoder, a Reed-Solomon decoder, a descrambler (energy dispersal) and a deinterleaver. The device conforms to the MPEG-II transport layer protocol specified by ISO/IEC standard and FEC requirements of Digital Video Broadcasting (DVB) DT/8622/DVB and DT/8610/ III-B specification. These documents are referred to as the DVB specification.

The Viterbi decoder supports selectable code rates of 1/2, 2/3, 3/4, 5/6, 6/7 or 7/8 using industry standard puncturing algorithms. Viterbi decoded data rate is up to 62 Mbits/second at all code rates. The chip also performs byte alignment and block/ packet synchronization detecting sync bytes used in transmission. The descrambling function is selectable with a programmable seed or performed externally. Each functional block may be bypassed giving more flexibility to a system designer.

Block size programmability, several code rate choices and programmable RS error correction capability allows flexibility to a digital communications system designer incorporating Forward Error Correction into a receiver. Intel 80C188 multiplexed parallel or serial I²C protocol interface allows the system microprocessor to program internal registers and monitor channel performance.
