TDA4855

INTEGRATED CIRCUITS DATA SHEET TDA4855 Autosync Deflection Controller (ASDC) Preliminary specification File under Integrated Circuits, IC02 1996 Jul 18 Philips Semiconductors Preliminary specification Autosync Deflection Controller (ASDC) 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 Horizontal focus parabola with amplitude control 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. Horizontal section Extremely low jitter Frequency locked loop for smooth catching of line frequency Simple frequency preset of fmin and fmax by external resistors DC controllable wide range linear picture position Soft start for horizontal driver. Vertical section TDA4855 Vertical amplitude independent of frequency Automatic correction of picture height for VGA350 and VGA400 modes DC controllable picture height, pictur...
