DATA SHEET  
FEATURES  
DEVICE DESCRIPTION  
• built-in 75 cable driver with two serial outputs  
• standard independent operation  
• space saving 28 pin PLCC package  
TheGS9022isamonolithicbipolarintegratedcircuitdesigned  
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  
NRZIserialdata. Thedatarateisautomaticallyset forSMPTE  
259M data rates to 400 Mb/s. Other features include a lock  
detect output and an internal cable driver capable of driving  
two 75loads.  
• 650 mW typical power dissipation (data output  
driving 75 load).  
• supports bit rates to 400 Mb/s  
• accepts 8 bit and 10 bit TTL and CMOS  
compatible parallel data inputs  
The device 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.  
• fully compatible with SMPTE 259M serial digital  
standard  
• single +5 or -5 volt supply
