www.DataSheet4U.com comtech aha corporation PRODUCT BRIEF AHA4524 (4 Kbit Block Version) TURBO PRODUCT CODE ENCODER/DECODER The AHA4524 device is a single-chip Turbo Product Code (TPC) Forward Error Correction (FEC) Encoder/Decoder. This device integrates independent TPC encoder and decoder functions, and can be configured for full or half duplex operation. In addition to TPC coding, the device includes helical interleaving, CRC computation, and data scrambling. Each of the functional blocks can be independently bypassed. Figure 1 shows the functional block diagram. The encoder and decoder accept data and configuration through a synchronous 3-wire or data bus interface designed to connect directly to a DSP or user logic.
