2 / 60 page 1999 Oct 25 2 Philips Semiconductors Product specification I2C-bus autosync deflection controller for PC monitors TDA4841PS FEATURES Concept features • Full horizontal plus vertical autosync capability • Extended horizontal frequency range from 15 to 130 kHz • Comprehensive set of I2C-bus driven geometry adjustments and functions, including standby mode • Very good vertical linearity • Moire cancellation • Start-up and switch-off sequence for safe operation of all power components • X-ray protection • Power dip recognition • Flexible switched mode B+ supply function block for feedback and feed forward converter • Internally stabilized voltage reference • Drive signal for focus amplifiers with combined horizontal and vertical parabola waveforms • DC controllable inputs for Extremely High Tension (EHT) compensation • SDIP32 package. Synchronization • Can handle all sync signals (horizontal, vertical, composite and sync-on-video) • Output for video clamping (leading/trailing edge selectable by I2C-bus), vertical blanking and protection blanking • Output for fast unlock status of horizontal synchronization and blanking on grid 1 of picture tube. Horizontal section • I2C-bus controllable wide range linear picture position, pin unbalance and parallelogram correction via horizontal phase • Frequency-locked loop for smooth catching of horizontal frequency • Simple frequency preset of fmin and fmax by external resistors • Low jitter • Soft start for horizontal and B+ control drive signals. Vertical section • I2C-bus controllable vertical picture size, picture position, linearity (S-correction) and linearity balance • Output for I2C-bus controllable vertical sawtooth and parabola (for pin unbalance and parallelogram) • Vertical picture size independent of frequency • Differential current outputs for DC coupling to vertical booster • 50 to 160 Hz vertical autosync range. East-West (EW) section • I2C-bus controllable output for horizontal pincushion, horizontal size, corner and trapezium correction • Optional tracking of EW drive waveform with line frequency selectable by I2C-bus. Focus section • I2C-bus controllable output for horizontal and vertical parabolas • Vertical parabola is independent of frequency and tracks with vertical adjustments • Horizontal parabola independent of frequency • Adjustable pre-correction of delay in focus output stage. |
