The Model PCI 650 FSVU (Frame Synchronization Verification Unit) contains eight PCM Decommutators that are designed for PCM stream quality verification rather than data processing. Each decommutator contains a minor frame synchronizer with a 64 bit pattern correlator, a 16 bit counter that counts the number of bits per frame, and a programmable synchronizer strategy providing Search, Verify, and Lock states. A programmable watchdog timer returns a decommutator to Search if the input clock is lost. You can read the status of each of the eight decommutators over the PCI bus to determine the quality of the input data to each channel.
