STV2000

STV2000 I2C SINGLE FREQUENCY DEFLECTION PROCESSOR AND 70 MHz RGB PREAMPLIFIER PRELIMINARY DATA FEATURES Horizontal deflection s Single frequency, self adaptive oscillator. s TTL compatible positive going sync. 2 s I C controlled: H-position, Pin Cushion, Keystone, Parallelogram, Side Pin Balance,Hamplitude. s DC East/West feedback. s DC controls: H-width breathing compensation. s X-Ray protection Vertical deflection s Vertical ramp generator. s Wide range AGC loop. s TTL compatible positive going sync, no extra pulses. 2 s I C controls: vertical position and S-correction. s DC controls: height breathing compensation. Video preamplifier s 3-channel 70MHz bandwidth RGB preamplifier. s 5ns typical rise and fall time at 4VPP. 2 s I C controls: RGB contrast, cut-off, brightness, contrast up-date during vertical retrace time. s ABL will reduce gain (contrast). s 0.514V typical video input signal for normal display. I2C Main features 2 s I C interface (slave) 100kHz max. 2 s All I C controlled DAC are 7bit, except for RGB gain and cut-off. s Power- on- reset at 5 V (VDD). s 0.5 to 4 V static DAC output. Supply voltage & power s 5 V/10.5 V dual supply. s Max power consumption: 1.2W 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. TQFP44 ORDER CODE : PIN CONNECTIONS FIL...
