GENERAL DESCRIPTION :

The VSC7148 is typically used to distribute Fibre Channel signals to an array of disk drives in managed and un- managed arrays. The use of an I2C Interface allows access to status information and control of configuration through an easily-implemented, industrystandard, protocol.

FEATURES :

► All the Functionality Needed to Implement a Complete DaisyChainable 16-drive 1 Gb/s FC-AL JBOD Subsystem

► Two Host Ports with Two Pairs of FibreTimer™ Clock Recovery Units (CRUs) Configurable as Either Repeaters or Retimers

► Sixteen Port Bypass Circuits (PBC) for Drive Control

► Sixteen PBC Internal Snoop Loop™ for Loop Diagnostics

► Configurable as Either a Single 16-drive Loop or Two 8-drive Loops

► I2C Interface for Configuration/Status/Control

► Seamless Interface to Enclosure Management Chipsets such as the Vitesse SSC100/VSC120/VSC055 for Managed JBOD Applications

APPLICATIONS :

► 1.0625 Gb/s FC-AL JBODs
