TDA4882中文资料Advanced monitor video controller for OSD数据手册恩XP规格书

描述 Description

GENERAL DESCRIPTION
The TDA4882 is an RGB pre-amplifier for colour monitor systems with SVGA 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 TDA485x monitor deflection IC family.FEATURES
• 85 MHz video controller
• 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
• On Screen Display (OSD) facility.
