AHAG709D-40FEC

www.DataSheet4U.com comtech aha corporation PRODUCT BRIEF AHA G709D-40 FEC Core 40 GB/S ITU G.709 REED-SOLOMON DECODER The G709D-40 core implements the 16 block interleaved RS(255,239) code specified by in Annex A of the ITU G.709 standard. The G709D-40 core is specifically designed to efficiently perform the Reed-Solomon decoding function specified by the standard. The core requires no configuration, no initialization, and no re-synchronization procedure or includes any unnecessary features that would add area, power or complexity to your design. A G709E Reed-Solomon encoder core is also available from AHA. FEATURES ITU G.709 compatible Reed-Solomon core Input and output data streams are blockinterleaved for seamless connection in G.709 system 40 Gbits/sec operation in 0.13µ CMOS process 220 Kgates in 0.13µ using a typical standard cell library One-edge, one-clock fully synchronous design without multi-cycle paths Separate FIFO for increased flexibility and simplified IC floor planning Complete error reporting for Bit Error Rate calculation and feedback into threshold detection circuits Figure 1: AHA G709D-40 FEC correct_to_zero[10:0] reset clk start received_data[127:0] correct_to_one[10:0] status_valid AHA G709D-40 FEC decode_complete uncorrectable[15:0] decoded_data[127:0] FIFO – 64 Kbit (available from AHA) comtech aha corporation fifo_data[127:0] comtech aha corporation INPUT SIGNALS clk - 332 MHz core clock.
