VSC7166

The VSC7166 is used to interface between OC-192 Framers and Parallel Optical Modules. In the Serializer, 16-bit OC-192 data from the Framer is mapped and encoded onto twelve 1.244 Gb/s, 8b/10b outputs, with 1 of the twelve outputs being used for XOR protection and another of the twelve for EDC. In the Deserializer, the twelve 1.244 Gb/s inputs are decoded and remapped to SFI-4 OC-192 data for the Framer. The redundant channel permits data to be reconstructed in the deserializer even if a channel fails. The 16- bit 622 MHz signals and the 12 1.244 Gb/s interfaces both utilize LVDS signaling. These devices are intended for high-speed Router-to-Router and DWDM/Sonet Terminal-to-Router connections.

The VSC7166 is designed to conform to the Optical Internetworking Forum's (OIF) OIF-VSR4-01.0 Implementation Agreement.
