General Description
The PCIe-SIO4BX2 is a four channel serial interface card which provides high speed, full-duplex, multi-protocol
serial capability for PCIe applications. The PCIe-SIO4BX2 combines multi-protocol Dual Universal Serial
Controllers, deep external FIFOs, and software selectable multi-protocol transceivers to provide four fully
independent synchronous/asynchronous serial channels. These features, along with a high performance one lane
PCIe interface engine, give the PCIe-SIO4BX2 unsurpassed performance in a serial interface card.
Features:
One Lane PCI Express (PCIe) Interface
Four Independent RS422/RS485/RS232 Serial Channels
Serial Mode Protocols - Asynchronous, Monosync, Bisync, SDLC, HDLC, Nine-Bit, IEEE 802.3
Synchronous Serial Data Rates up to 10Mbps
Asynchronous Serial Data Rates up to 1Mbps
Independent Transmit and Receive FIFOs for each Serial Channel – 32K byte each
Multi-protocol Transceivers support RS422/RS485 and RS232
