VSC9210
Features:
Reed Solomon RS(255,241) Codec Error Rate Improvement from 1020 Includes Optical Channel Overhead (OCh-OH) 10Mb/s Provides Error Rate Monitoring Line Processes Data Rates 2.654Gb/s Information Rates 2.488Gb/s Provides Dedicated User Defined Data Channel 10.368Mb/s
Product Description
VSC9210 provides forward error correction data rate protocol operating 2.5Gb/s using block oriented Reed-Solomon Forward Error Correction (FEC) algorithm RS(255,241). device configured encoder decoder utilizing 16-bit differential PECL ports interface with external high speed multiplexer/ demultiplexer pair. Clock dividers provided chip facilitate control external circuitry. Encoder, 1:16 Demultiplexer used convert incoming 2.5Gb/s STS-48 information parallel data 155MHz interface with VSC9210. After encoding process, parallel output data from VSC9210 obtained 165MHz converted 2.65Gb/s data stream using 16:1 Multiplexer. case Decoder configuration, Demultiplexer operates 2.65Gb/s data stream while Multiplexer provides 2.5Gb/s STS-48 information stream. Clock dividers incorporated within VSC9210 provide control external circuit synthesizing necessary reference clock Multiplexer. case Bypass mode, input output rates identical both Multiplexer Demultiplexer operate 2.5Gb/s.
Benefits:
Device Configured Stand-alone Encoder, Decoder, Bypass with Cocks Disabled Provides Count Correctable that Error Prior Code Word Interfaces Directly with Vitesse OC-48 Rate Components
