INTEGRATED CIRCUITS DATA SHEET TDA4852 Horizontal and vertical deflection controller for autosync monitors Preliminary specification File under Integrated Circuits, IC02 December 1992 Philips Semiconductors Preliminary specification Horizontal and vertical deflection controller for autosync monitors FEATURES · Low jitter · All adjustments DC-controllable · Alignment-free oscillators · Sync separators for video or horizontal and vertical TTL sync levels regardless of polarity · Horizontal oscillator with PLL1 for sync and PLL2 for flyback · Constant vertical and E/W amplitude in autosync operation · DC-coupling to vertical power amplifier · Internal supply voltage stabilization with excellent ripple rejection to ensure stable geometrical adjustments GENERAL DESCRIPTION TDA4852 The TDA4852 is a monolithic integrated circuit for economical solutions in autosync monitors. The IC incorporates the complete horizontal and vertical small signal processing. In conjunction with TDA4860/61/65, or TDA8351 (vertical output circuits) the ICs offer an extremely advanced system solution.
