Description

The GS9022 is a monolithic bipolar integrated circuit designed to serialize SMPTE 125M and SMPTE 244M bit parallel digital signals as well as other 8 or 10 bit parallel formats. GS9022 performs the functions of 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 data rate of GS9022 is automatically set   for SMPTE 259M data rates to 400 Mb/s.  Other features include a lock detect output and an internal cable driver capable of driving two 75Ω loads.

The GS9022 requires a single +5 volt or -5 volt supply and typically consumes 650 mW of power while driving two 75 Ω loads. The 28 pin PLCC packaging assures a small footprint for the complete encoder function.
