This product is discontinued, please see P/N 9136 for our form-fit-function “Tech Refresh” product. Our Enhanced Reconfigurable 32-Channel RS485/RS422 Differential I/O FPGA-Based PMC (4289) provides a vehicle for implementing complex user-specific digital designs requiring a differential interface.
Product Information
The Technobox, Inc P/N 4289 provides a vehicle for implementing complex user-specific digital designs requiring a differential interface. It is a second-generation design that features 64b/66MHz PCI bus support, up to 66 MHz local bus clock, and a standard 12K Logic Elements (LE) FPGA.
The design features a total of 32 general-purpose RS422/RS485 driven digital I/Os wired to both the front panel and rear PN4 connector (64 signals per connector taking into account 2 signals per differential pair). For each of the 32 channels, the bi-directionality is controlled by an output from the FPGA. Local bus clock is selectable as 24, 33, 50, or 66 MHz using resistor jumpers. Any frequency with better than 0.1% accuracy can be generated by the PLL as programmed from the host processor.
