DESCRIPTION

The STV2145 is an I

2C 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. STV2145 has been designed

to drive a standard TDA8172/8177 vertical booster

and an external transistor for East-West.
