GS1500 Description
When interfaced to the Gennum GS1545 HDTV Equalizing Receiver or GS1540 Non-Equalizing Receiver, the GS1500 performs the final conversion to word aligned data. The device performs NRZI decoding and de-scrambling as per SMPTE 292M and word-aligns to the ining data stream. Line based CRCs are calculated on the ining data stream and are pared against the CRCs embedded within the data stream.
