High Performance Serial Backplane Transceiver

The VSC870 serial Backplane transceiver has been designed to operate with the VSC880 serial crosspoint Switch to establish a synchronous high performance switching system. The VSC870 CAN also connect directly to another transceiver to act as a high bandwidth Backplane interconnect link. The transmitter converts a 32-bit parallel Interface operating at 62.5Mb/s to a 34-bit serial data stream operating a 2.125Gb/s. The receiver converts a 34-bit serial Interface operating at 2.125Gb/s to a 32-bit parallel Interface operating at 62.5Mb/s. The transceiver performs Automatic bit alignment, word alignment and cell alignment to a connected Switch chip or another transceiver. The parallel Interface has been designed with industry-standard FIFOs in mind to provide such features as Automatic packet retransmission, multicast with retransmission, camp-on and support for virtual output queues. These features CAN also be bypassed to give the user direct control of the serial data stream. In addition, the transceiver and Switch chip CAN operate in a early arbitration mode that greatly improves bandwidth utilization. The transceiver also contains a built-in a flow control channel and redundant serial I/O Buffers By Vitesse Semiconductor Corp
