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