... Dual Digital Signal Detect Units (SDUs) 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 confi ...
