STMicroelectronics STV9212

The STV9212 is an I²C-bus controlled color video processor designed for standard CRT monitor applications. It can drive systems where cathodes are either AC- or DC-coupled to the amplifier outputs. The three video channels provide contrast and white balance separate gain adjustments as well as one-per-channel DC cut-off control and common DC offset control functions.

GENERAL DESCRIPTION

On top of these usual controls, it features context-sensitive picture enhancement circuitry to support the PictureBooST™ function that enhances the appearance of still pictures and moving video. In AC coupling applications, the device can pilot three cathode DC restore channels dedicated to set CRT cut-off bias voltages and to control brightness through cathodes.
