2 / 44 page 1997 Oct 27 2 Philips Semiconductors Product specification Economy Autosync Deflection Controller (EASDC) TDA4858 FEATURES Concept features • Full Horizontal (H) plus Vertical (V) autosync capability • Completely DC controllable for analog and digital concepts • Excellent geometry control functions [e.g. automatic correction of East-West (EW) parabola during adjustment of vertical size and vertical shift] • Flexible Switched Mode Power Supply (SMPS) function block for feedback and feed forward converters • X-ray protection • Start-up and switch-off sequence for safe operation of all power components • Very good vertical linearity • Internal supply voltage stabilization • SDIP32 package. Synchronization inputs • Can handle all sync signals (horizontal, vertical, composite and sync-on-video) • Combined output for video clamping, vertical blanking and protection blanking • Start of video clamping pulses externally selectable. Horizontal section • Extremely low jitter • Frequency locked loop for smooth catching of line frequency • Simple frequency preset of f min and fmax by external resistors • DC controllable wide range linear picture position • Soft start for horizontal driver. Vertical section • Vertical amplitude independent of frequency • DC controllable picture height, picture position and S-correction • Differential current outputs for DC coupling to vertical booster. EW section • Output for DC adjustable EW parabola • DC controllable picture width and trapezium correction • Optional tracking of EW parabola with line frequency • Prepared for additional DC controls of vertical linearity, EW-corner, EW pin balance, EW parallelogram, vertical focus by extended application. GENERAL DESCRIPTION The TDA4858 is a high performance and efficient solution for autosync monitors. The concept is fully DC controllable and can be used in applications with a microcontroller and stand-alone in rock bottom solutions. The TDA4858 provides synchronization processing, H + V synchronization with full autosync capability, and very short settling times after mode changes. External power components are given a great deal of protection. The IC generates the drive waveforms for DC-coupled vertical boosters such as TDA486x and TDA8351. The TDA4858 provides extended functions e.g. as a flexible SMPS block and an extensive set of geometry control facilities, providing excellent picture quality. Together with the Philips TDA488x video processor family a very advanced system solution is offered.
