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.

FEATURES

• ITU G.709 compatible Reed-Solomon core

• Input and output data streams are block-

interleaved 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

A G709E Reed-Solomon encoder core is also

available from AHA.

• Separate FIFO for increased flexibility and

simplified IC floor planning

• Complete error reporting for Bit Error Rate

calculation and feedback into threshold detection

circuits
