PB-VSC7147-002 VSC7147 VSC7147 and VSC7147-01 - Hex PBC with Dual Repeater/Retimer GENERAL DESCRIPTION: The VSC7147 expands Vitesse's wide offering of Fibre Channel products with an IC for the growing 2.125Gb/s Fibre Channel storage market. The device features six Port Bypass Circuits (PBC) that support both 1.0625Gb/s and 2.125Gb/s Fibre Channel data rates. The VSC7147 enables Fibre Channel Disk Arrays, JBODs (Just a Bunch of Disks) and storage subsystem equipment designers to integrate more ports and disk drives and maintain consistently high signal quality using fewer components. In addition to the PBCs that steer serial Fibre Channel signals to disk drives and bypass faulty ports, the VSC7147 features dual FibreTimer Repeater/Retimer cells. V S C 7 1 4 7 A P P L I C AT I O N S : Each FibreTimer cell contains an all-digital clock recovery unit (CRU) that can be configured as either a Repeater or a Retimer. In the repeater mode, recovered data is retransmitted to a recovered clock, allowing for improved jitter attenuation and low latency. In the retimer mode, recovered data is re-transmitted synchronously to a local reference clock with no jitter transfer ensuring compliance to Fibre Channel signal quality specifications. The VSC7147-01 adds an analog signal detect (ASD) function which helps the signal detection capabilities of the Fiber TimersTM.
