Aitech’s S710 Communication PMC features RS-422 differential Inputs and RS-422 differential Outputs with onboard FPGA logic to interface to the external spacecraft sensors and devices. The incoming data is parsed and stored in a ring buffer or dual buffer modes with a triple-voted mechanism to mitigate single event upset to the on board memory buffer. The S710 also provides for an IEEE-1394a communications interface with 3 physical ports. The FireWire ports are designed to provide DMA capability to local PCI memory. The S710 is a singlewide conduction-cooled PCI mezzanine card (PMC) with a 33.333 MHz 32-bit PCI interface.
