Advance Product Information
VSC7124
Quad Port Bypass Circuit
Features
ANSI X3T11 Fibre Channel Compliant at 1.0625Gb/s
General Description
The VSC7124 contains five cascaded Port Bypass Circuits (PBCs) used to steer serial signals. This part is typ-
ically used in distributing Fibre Channel signals to an array of disk drives in an FC-AL loop as illustrated in Fig-
ure 1. The VSC7124 can be used with any of the Vitesse JBOD circuits to implement FC-AL JBODs of
virtually any size. In Figure 1, the first VSC7127’s CRU is configured as a Repeater to attenuate jitter. The
VSC7124 does not contain a CRU in order to reduce power and cost. The second VSC7127’s CRU is config-
ured as a retimer so that the output of the device is a jitter compliance point.
Each PBC is a multiplexer that is controlled by the corresponding SELx line which, if HIGH, selects the exter-
nal input or, if LOW, selects the output of the previous PBC.
