STV2000
I2C SINGLE FREQUENCY DEFLECTION PROCESSOR AND
70 MHz RGB PREAMPLIFIER
PRELIMINARY DATA
FEATURES
Horizontal deflection
s Single frequency, self adaptive oscillator.
s TTL compatible positive going sync.
s I2C controlled: H-position, Pin Cushion,
Keystone, Parallelogram, Side Pin Balance,H-
amplitude.
s DC East/West feedback.
s DC controls: H-width breathing compensation.
s X-Ray protection
Vertical deflection
s Vertical ramp generator.
s Wide range AGC loop.
s TTL compatible positive going sync, no extra
pulses.
s I2C controls: vertical position and S-correction.
s DC controls: height breathing compensation.
Video preamplifier
s 3-channel 70MHz bandwidth RGB preamplifier.
s 5ns typical rise and fall time at 4VPP.
s I2C controls: RGB contrast, cut-off, brightness,
contrast up-date during vertical retrace time.
s ABL will reduce gain (contrast).
s 0.514V typical video input signal for normal
display.
I2C Main features
s I2C interface (slave) 100kHz max.
s All I2C controlled DAC are 7bit, except for RGB
gain and cut-off.
s Power- on- reset at 5 V (VDD).
s 0.5 to 4 V static DAC output.
Supply voltage & power
s 5 V/10.5 V dual supply.
s Max power consumption: 1.2W
DESCRIPTION
The STV2000 is an I2C-controlled monolithic
integrated circuit assembled in a TQFP44 plastic
package. It combines both a deflection block
(horizontal and vertical, single frequency with very
powerful geometry correction) and a 70MHz RGB
pre-amplifier.
