The OP4610-IO is a compact OP4xxx I/O expansion unit that is compatible with our OP4605XG2 & OP4610XG2 simulators, as well as certain previous generations of devices. Powered by an AMD Kintex™-7 FPGA, it offers 128 fast I/O channels with signal conditioning, 12 RS422 or low-speed fiber optic channels, and 4 high-speed SFP communication ports. It connects to the simulator through a point-to-point standard PCIe interface and also supports LVDS or fiber optic synchronization, enabling easy integration with any OPAL-RT device.
