Advance Product Information
VSC7128
Hex Port Bypass Circuit / Dual Repeater
for 1.0625 Gb/s FC-AL Disk Arrays
G52177-0, Rev. 2.3
Features
Supports ANSI X3T11 1.0625Gb/s FC-AL Disk
Attach for Resiliency
General Description
The VSC7128 contains six Port Bypass Circuits (PBCs), dual embedded Clock Recovery Unit repeaters
(CRU) and dual Signal Detect Units (SDU). These functions are integrated into a single part to minimize circuit
size, part count, cost, high frequency routing and jitter accumulation. Together, they allow for optimized designs
of FC-AL JBOD systems that provide resiliency and hot insertion/removal of disk drives. The PBCs configure
the FC-AL loop to either include or exclude each drive. Repeaters retime the incoming signal thereby attenu-
ating jitter so that downstream devices see high amplitude, low jitter signals. The SDUs determine whether the
output of the CRU is a valid Fibre Channel signal. Disk drives are connected directly to the LSO/LSI/SEL pins
while the IN/OUT pins can be connected to any FC-AL devices.
