DESCRIPTION  
The STV2145 is an I2C bus processor containing  
the vertical deflection East-West functions and  
oversize blanking. This circuit is foreseen as ADD-  
ON for the Video Chroma Processor STV2118A  
to permit 110° CRT applications covering standard  
4/3 screen format and new 16/9 format with zoom  
and subtitle facilities. STV2145has been designed  
to drive a standard TDA8172/8177vertical booster  
and an external transistor for East-West.
