GS1510-CQR 128 pin MQFP 0°C to 70°C DESCRIPTION When interfaced to the Gennum GS1545 HDTV Equalizing Receiver or GS1540 Non-Equalizing Receiver, the GS1510 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 incoming data stream. Line based CRCs are calculated on the incoming data stream and are compared against the CRCs embedded within the data stream. HVF timing information is extracted from the data stream. A selectable internal HVF flywheel provides superior noise immunity against TRS signal errors. The device also detects and indicates the input video signal standard. The GS1510 can detect and...
