PRODUCT BRIEF

AHA G709D-10 FEC Core

10 GB/S ITU G.709

REED-SOLOMON DECODER

After more than 15 years building leading edge

FEATURES

Reed-Solomon ICs, AHA is licensing its patented

technology for the first time. The G709D-10 core

implements the 16 block interleaved RS(255,239)

code specified by in Annex A of the ITU G.709

standard.

• ITU G.709 Compatible Reed-Solomon core

• Input and output data streams are block-

interleaved for seamless connection in G.709

system

The G709D-10 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.

• 10 Gbits/sec operation in 0.18µ CMOS process

• 140 Kgates in 0.18µ using a typical standard cell

library

• Less than 100 mA of dynamic current in UMC's

0.18µ CMOS process

• One-edge, one-clock fully synchronous design

without multi-cycle paths

A complementary G709E RS encoder 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
