AHA4540B Description
tech aha corporation PRODUCT BRIEF AHA4540B 155 MBITS/SEC TURBO PRODUCT CODE ENCODER/DECODER The AHA4540 device is a single-chip Turbo Product Code (TPC) Forward Error Correction (FEC) Encoder/Decoder capable of 155 Mbit/sec (OC-3) data rates (up to 200 Mbit/sec channel rates). This device integrates both a TPC encoder and decoder, and can be operated in a full duplex mode. In addition to TPC coding, support is...
