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
