The GS7032 is designed to encode and serialize SMPTE 125M bit parallel digital video signals as well as other 8-bit or 10-bit parallel formats. This device performs the following functions:
sync detection
parallel to serial conversion
data scrambling (using the X9 + X4 + 1 algorithm)
10x parallel clock multiplication
conversion of NRZ to NRZI serial data
The GS7032 features 270M/bs data rate with a single VCO resistor. Other features include a lock detect output, NRZI encoding and SMPTE scrambler bypass, a sync detect disable, and an isolated dual output cable driver suitable for driving 75ohm loads.
SMPTE 259M-C compliant (270Mb/s)
serializes 8-bit or 10-bit data
minimal external components (no loop filter components required)
isolated, dual-output, adjustable cable driver
3.3V and 5.0V CMOS/TTL compatible inputs
lock detect indication
SMPTE scramble and NRZI coding bypass option
SMPTE 259M-C parallel to serial interfaces for video cameras, VTRs, signal generators; Generic parallel to serial conversion.
