By isolating the system clock and transmitting an extremely low jitter high quality clock to downstream devices, the PXH810 offers users high signal quality and increased cable distances. The combination of RDMA and PIO creates a highly potent data transfer system.
The PXH810 performs both Remote Direct Memory Access (RDMA) and Programmed IO (PIO) transfers, effectively supporting both large and small data packets. The overall framework is designed for rapid development of inter-processor communication systems.
PIO transfers optimize small packet transfers at the lowest latency. With the implementation of clock isolation, the PXH810's signal quality is excellent. Fiber optics is supported up to 100 meters at full speed. The PXH810 is carefully designed for maximum cable length and support copper cables up to 5 meters at full PCI Express Gen3 speed when connected to another PXH810 card.
