OC-192 SONET Frame Transport Mechanisms Converts LVDS Inputs 622Mb/s into 8B10B Encoded LVDS Outputs 1.244Gb/s Converts LVDS Inputs 1.244Gb/s into LVDS Outputs 622Mb/s Conforms OIF99.120 8b/10b Encoder/Decoder Channel Diagnostic Error Injection Insertion/Recognition Framing Patterns
OC-192 16:12 SerDes
Channel-to-Channel Deskewing Receiver Redundant Channel Fault Tolerance Patchcord Reversal Protection Channel Error Detection Loss Synchronization State Machine 1.8V 2.5V Supplies Power 256-pin, 27mm Package
General Description
VSC7166 used interface between OC-192 Framers Parallel Optical Modules. serializer, 16bit OC-192 data from Framer mapped encoded onto twelve 1.244Gb/s, 8b/10b outputs, with outputs being used protection another twelve EDC. deserializer, twelve 1.244Gb/s inputs decoded remapped 16-bit OC-192 data Framer. redundant channel permits data reconstructed deserializer even channel fails. These devices intended highspeed router-to-router DWDM/SONET terminal-to-router connections. VSC7166 conforms Optical Internetworking Forum's Proposal Very Short Reach (VSR) OC-192 Interface Based Parallel Optics OIF-99.120.
