General Description

The VSC880 is a 16x16 serial crosspoint switch with serial data rates at 2.125Gb/s. The VSC880 has been designed to operate with the VSC870 backplane transceiver to establish a synchronous high performance switching system with an aggregate bandwidth of 32Gb/s. The switch chip transmits the master word clock (62.5Mb/s), and master cell clock (if used) to all port cards through the serial data channels. The transceivers automatically perform bit alignment, word alignment and cell alignment to the switch chip.
