TDA4689

INTEGRATED CIRCUITS DATA SHEET TDA4689 Video processor with automatic cut-off control Product specification File under Integrated Circuits, IC02 1997 Jul 01 Philips Semiconductors Product specification Video processor with automatic cut-off control FEATURES Operates from an 8 V DC supply Black level clamping of the colour difference, luminance and RGB input signals with coupling-capacitor for DC level storage Two analog RGB inputs, selected either by fast switch signals or via I2C-bus; brightness and contrast control of both RGB inputs Saturation, contrast, brightness and white adjustment via I2C-bus Same RGB output black levels for Y/CD and RGB input signals Timing pulse generation from either a 2 or 3-level sandcastle pulse for clamping, vertical synchronization and cut-off timing pulses Automatic cut-off control or clamped output selectable via I2C-bus Automatic cut-off control with picture tube leakage current compensation Cut-off measurement pulses after end of the vertical blanking pulse or end of an extra vertical flyback pulse Ultra-black or nominal black blanking selectable via I2C-bus in clamped output mode Two switch-on delays to prevent discolouration before steady-state operation Average beam current and peak drive limiting PAL/SECAM or NTSC matrix selection via I2C-bus Emitter-follower RGB output stages to drive the video output stages I2C-bus controlled DC output e.g. for hue-adjust of NTSC (multistandard) decoders Positive am...
