Advanced monitor video controller
Preliminary specification
TDA4881
FEATURES
Fully DC controllable
3 separate video channels
Input black level clamping
White level adjustment for 2 channels only
Brightness control with correct grey scale tracking
Contrast control for all 3 channels simultaneously
Cathode feedback to internal reference for cut-off
control, which allows unstabilized video supply voltage
Current outputs for RGB signal currents
RGB voltage outputs to external peaking circuits
Blanking and switch-off input for screen protection
Sync on green operation possible
GENERAL DESCRIPTION
The TDA4881 is a monolithic integrated RGB amplifier for
colour monitor systems with super VGA performance,
intended for DC or AC coupling of the colour signals to the
cathodes of the CRT. With special advantages the circuit
can be used in conjunction with the TDA4851.
