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 multi-  
plexer forms a Port Bypass Circuit (PBC) to route either recovered incoming data or SI to SO.  
Fibre Channel subsystems requiring signal cleanup at the bulkhead would connect RX1 to the incoming  
signal and SO1 to the internal subsystem’s input. RX2 would connect to the output of the subsystem and SO2  
would connect to the bulkhead.  
For Hub applications, SI would connect to the previous Hub Node and output data to the external device on  
TX. Incoming data from the external device on RX is recovered and cleaned up and passed to the next Hub  
node on SO. If the external device is not functional, SI is passed to SO.
