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

FEATURES

Horizontal deflection

■ Single frequency, self adaptive oscillator.

■ TTL compatible positive going sync.

■ I2C controlled: H-position, Pin Cushion, Keystone, Parallelogram, Side Pin Balance,Hamplitude.

■ DC East/West feedback.

■ DC controls: H-width breathing compensation.

■ X-Ray protection Vertical deflection

■ Vertical ramp generator.

■ Wide range AGC loop.

■ TTL compatible positive going sync, no extra pulses.

■ I2C controls: vertical position and S-correction.

■ DC controls: height breathing compensation.

Video preamplifier

■ 3-channel 70MHz bandwidth RGB preamplifier.

■ 5ns typical rise and fall time at 4VPP.

■ I2C controls: RGB contrast, cut-off, brightness, contrast up-date during vertical retrace time.

■ ABL will reduce gain (contrast).

■ 0.514V typical video input signal for normal display.

I2C Main features

■ I2C interface (slave) 100kHz max.

■ All I2C controlled DAC are 7bit, except for RGB gain and cut-off.

■ Power- on- reset at 5 V (VDD).

■ 0.5 to 4 V static DAC output.

Supply voltage & power

■ 5 V/10.5 V dual supply.

■ Max power consumption: 1.2W
