The PMC-4U features the Exar 854 quad UART and Zilog 85X30 Serial Communications Controller. The PMC-4U utilizes a Xilinx FPGA to provide a 33/32 PCI interface and control for the UART and SCC. The IO from the Quad UART and Serial Communications
Controller are routed through the FPGA to provide a multiplexer capability with the IO options onboard. The PMC-4U supports RS232, RS485, RS423 and RS188. The PMC-4U has options for the UART and SCC reference frequencies, and the capability of adding a reference oscillator to the Xilinx for custom state machine requirements. Perfect for your embedded control applications! A high-density
68 pin SCSI III front panel connector and backplane IO provide system wiring options.
