General Description

The VSC7140 is a dual Fibre Channel repeater which can be used in Hubs, JBODs or any Fibre Channel Subsystem requiring clean incoming and outgoing signals at a bulkhead connector. The digital Clock Recovery Unit (CRU) recovers incoming data from an external device, amplifies it and attenuates jitter. A digital Signal Detect Unit (SDU) determines whether the incoming signal contains invalid Fibre Channel data. A 2:1 multiplexer forms a Port Bypass Circuit (PBC) to route either recovered incoming data or SI to SO.
