The GS9032 encodes and serializes SMPTE 125M and 244M bit parallel digital video signals, and other 8-bit or 10-bit parallel formats. This device performs sync detection, parallel to serial conversion, data scrambling (using the X9 + X4 + 1 algorithm), 10x parallel clock multiplication and conversion of NRZ to NRZI serial data. The GS9032 features auto standard and adjustment free operation for data rates to 540Mb/s with a single VCO resistor. Other features include a lock detect output, NRZI encoding, SMPTE scrambler bypass, a sync detect disable, and an isolated quad output cable driver suitable for driving 75ohm loads. The complementary cable driving output swings can be adjusted independently or the secondary differential cable driver can be powered down.
The GS9032 requires a single +5 volt or -5 volt supply and typically consumes 675mW of power while driving four 75ohm loads.
