DESCRIPTION
DATA SHEET
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 75Ω loads.
