General Description

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. 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.

● Input and Output Video Clamp

● Sync Pulse Polarity Auto-rectification

● Clamp Pulse Generation timed either by sync

or video blanking pulse

■ Video Processing

● Contrast Adjustment with excellent channel

matching

● Gain stages for control of white

● Two DC-mode cut-off ranges

● Output DC offset control

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.

● Automatic Beam Limiter (ABL)

● Video Insertion Pulse (VIP), 2 levels

● Amplifier Control (Blanking and Stand-by)

■ OSD Insertion with Contrast Control

■ Control Output

The RGB video outputs have a class A architecture

and directly drive the amplifier channels without

unnecessarily consuming current. Bandwidth

limitation I²C-bus adjustments can contribute to

keeping the application EMI under control.

● Amplifier Standby and Blanking Control

● 3 DAC for control of DC Restore Amplifier or

OSD (On-Screen Display) graphics are inserted by

means of a Fast Blanking signal. Independent OSD

contrast control facilitates adaptation to various

OSD generators and provides system flexibility.

Brightness in DC-coupled system

The STV9212 is perfectly compatible with other ST

components for CRT video boards, such as video

amplifiers and OSD generators.
