DEFLECTION PROCESSOR FOR MULTISYNC MONITORS
1
DEFLECTION PROCESSOR
The KB2512 is a monolithic integrated circuit assembled in 32 pins
shrunk dual in line plastic package. This IC controls all the functions
related to the horizontal and vertical deflection in multi modes or multi-
frequency computer display monitors.
The internal sync processor, combined with the very powerful geometry
correction block make the KB2512 suitable for very high performance
monitors with very few external components. The horizontal jitter level is
very low. It is particularly well suited for high-end 17” and 19” monitors.
FUNCTIONS
Deflection processor
I2C bus control
B+ regulator
Vertical parabola generator
Vertical dynamic focus
FEATURES
(HORIZONTAL)
Self-adaptive
Dual PLL concept
150kHz maximum frequency
X-RAY protection input
I2C controls: Horizontal duty-cycle, H-position, free
running frequency, frequency generator for burn-in
mode.
(VERTICAL)
Vertical ramp generator
50 to 185Hz AGC loop
Geometry tracking with V-POS & V-AMP
I2C Controls: V-AMP, V-POS, S-CORR, C-CORR
DC breathing compensation
(I2C GEOMETRY CORRECTIONS)
Vertical parabola generator
(pincushion-E/W, keystone, corner)
32-SDIP-400
Horizontal dynamic phase (side pin balance &
parallelogram)
Vertical dynamic focus (Vertical focus amplitude)
(GENERAL)
Sync processor
12V supply voltage
Hor. & Vert. lock/unlock outputs
Read/Write I2C interface
Horizontal and vertical moire
B+ Regulator
- Internal PWM generator for B+ current mode
step-up converter.
- I2C adjustable B+ reference voltage
- Output pulses synchronized on horizontal
frequency
- Internal maximum current limitation.
- Soft start
Compared with the KB2511B, KB2512 HAS:
- Corner correction
- Horizontal moire
- B+ soft start
- Increased max. Vertical frequency
- No horizontal focus
- No step down option for DC/DC converter.
