Description

The STV2145 is an I2C bus processor containing the vertical deflection East-West functions and oversize blanking. This circuit is foreseen as ADDON 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 TDA8172/8177 vertical booster and an external transistor for East-West.
