General Dynamics / Veridian / Veda Systems 314-290125-300 PCI Decom Module

The General Dynamics/Veridian/Veda Systems 314-290125-300 is a PCI decommutator module that decodes individual parameters from serial PCM data streams. This PCI expansion card integrates three Altera Flex 10K programmable logic devices with an AMCC PCI Matchmaker S5935 local bus interface controller and four Cypress CY7C4275 32K x 18 deep synchronous FIFO buffers. The architecture enables real-time processing and temporary buffering of incoming PCM data before transmission to the host system.
