STV2001
I²C SINGLE FREQUENCY DEFLECTION PROCESSOR
AND 120 MHz RGB PREAMPLIFIER
TARGET SPECIFICATION
FEATURES
Horizontal deflection
s Single Frequency, Self Adaptive Oscillator.
s TTL compatible positive going sync.
s Chip does not accept sync on RGB or any video
signal.
s I²C controlled: H-position, pin cushion,
keystone, parallelogram, side pin balance.
s I²C controlled EW corner : top and bottom
corrections.
s I²C controlled corner: top and bottom phase
corrections.
s EW output
s I²C controlled H-amplitude
s DC controlled H-width breathing compensation
with I²C controlled gain (0.5x to 2x).
s Xray shut-down on ABL, H output latch, reset by
power OFF/ON.
s Soft start on H-duty.
Vertical deflection
s Vertical ramp generator.
s Wide range AGC loop.
s TTL compatible positive going sync, no extra
pulses.
s I²C controlled vertical position.
s I²C controlled S linearity correction.
s DC controlled height breathing compensation
with I²C controlled gain (0.5X TO 2X).
s Vertical dynamic focus output with fixed
amplitude (1Vpp).
Video preamplifier
s 3-Channel 120MHz bandwidth video amplifier.
s 3.5ns typical rise and fall time at 2.5V_PP.
s I²C controlled individual RGB contrast
(8bit)>8db
s I²C controlled overall brightness.
s Activation of ABL results in contrast gain
decrease.
s Gain window (1.5X) controlled by input pulse
and I²C. Pulse height controls the gain variation
from 1x to 1.5x.
s 0.514V typical video input signal for normal
display.
s I²C controlled contrast (7bits) update during
vertical retrace time.
I²C main features
s I²C interface (slave) 100kHz max.
s All I²C controlled DAC are 7 bits, except RGB
gain.
s Power on reset on 5 V (V_DD).
Supply voltage & power
s 5 V/10.5 V dual supply.
s Max power consumption: 1.2W
DESCRIPTION
The STV2001 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 120MHz
RGB pre-amplifier.
