The SI04BXR-SYNC board is a four channel serial interface card which provides a simple synchronous serial interface capability for PMC applications. The SIO4BXR-SYNC combines a flexible parallel/serial converter and 8 external FIFOs to provide four fully independent synchronous serial channels. These features, along with a high performance PCI interface engine, give the SIO4BX-SYNC unsurpassed performance in a serial interface card. The SIO4BX-SYNC features software configurable cable tranceivers (RS422, RS232 and others).
