VSC9901
Overview
10/100/1000BASE-T Copper PHY 65nm IP Core
Microsemi is a leading provider of transport processing technology with widely deployed 10G OTN Mapper devices that use enhanced FEC (eFEC). The Microsemi VSC9804 100G Continuously Interleaved BCH-4 (CI-BCH-4™) design package enables integration of eFEC encoder/decoder algorithms optimized for 100G OTN transport applications. The algorithms support the 20% FEC overhead ratio. FEC bytes are generated in the encoder using BCH-4 error correcting code. FEC byte locations in the OTU4 signal are overwritten with computed CI-BCH-4™ FEC bytes. The decoder applies hard-decision CI-BCH-4™ FEC decoding to a received OTU4 signal. The corrected OTU4 signal is delivered at the output of the decoder. Decoding latency can be varied for FEC error-correcting performance and reduced latency trade-offs. FEC statistic outputs such as corrected 1s, corrected 0s, and uncorrectable code words are generated for performance monitoring. The VSC9804 CI-BCH-4™ eFEC core can be targeted to ASIC implementations including support for 40G OTU3.
