PRODUCT BRIEF
AHA G709D-10 FEC Core
10 GB/S ITU G.709
REED-SOLOMON DECODER
After more than 15 years building leading edge
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.
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.
A complementary G709E RS encoder is also
available from AHA.
FEATURES
ITU G.709 Compatible Reed-Solomon core
Input and output data streams are block-
interleaved for seamless connection in G.709
system
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
Separate FIFO for increased flexibility and
simplified IC floor planning
Complete error reporting for Bit Error Rate
calculation and feedback into threshold detection
