DESCRIPTION

The TDA9206 is a digitaly controlled wideband video preamplifier intended for use in high resolution color monitor. All controls and adjustmentsare digitaly performed thanks to I2C serial bus. Contrast, brightness and DC output level of RGB signals are common to the 3 channels and drive adjustmentis separatefor each channel. Three I2C gain controlled OSD inputs can be switched with RGB signalsusing fast blanking command. Clamping of RGB signals is performed thanks to a flexible integrated system. The white balance adjustment is effective on brightness, video and OSD signals. The TDA9206works for application usingAC or DC coupled CRT driver.
