Preliminary specification
Horizontal and vertical deflection controller
for autosync monitors
TDA4852
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
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.
