LS-50-D PCI Multi-function PCM Decommutator offers a PCM decom, PCM simulator, time code reader/generator, and optional bit synchronizer in a single short PCI card slot. The multi-function decom and simulator are implemented in FPGA using a next generation design based on the LS-50-P. The simulator, decommutator, time code reader and time code generator are achieved on the main board and the bit synchronizer is achieved through an optional low-profile daughterboard. CVSD voice decoding, h.261 video decoding, and IRIG Chapter 8 decoding are achieved through software.
