DEVICE DESCRIPTION
DATA SHEET
The GS9022A is a drop-in replacement for the GS9022 in
existing applications
The GS9022A 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. This device
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 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 device requires a single +5 volt or -5 volt supply and
typically consumes 650 mW of power while driving two 75Ω
loads. The 28 pin PLCC packaging assures a small footprint
for the complete encoder function.
