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
