1 / 56 page  May 2004 1/56 This is preliminary information on a new product now in development. Details are subject to change without notice. Version 1.1 STV6889 HIGH-END I²C CONTROLLED DEFLECTION PROCESSOR FOR MULTISYNC MONITOR PRODUCT PREVIEW FEATURES General • Advanced I2C-bus controlled deflection processor dedicated for high-end CRT monitors • Single supply voltage 12V • Very low jitter • DC/DC converter controller • Advanced EW drive • Advanced asymmetry corrections • Automatic multistandard synchronization • Vertical dynamic correction waveform output • X-ray protection and Soft-start & stop on horizontal and DC/DC drive outputs •I2C-bus status register Horizontal section • 150 kHz maximum frequency • Corrections of geometric asymmetry: Pin cushion asymmetry, Parallelogram, separate Top/Bottom corner asymmetry • Tracking of asymmetry corrections with vertical size and position • Fully integrated horizontal moiré cancellation Vertical section • 200 Hz maximum frequency • Vertical ramp for DC-coupled output stage with adjustments of: C-correction, S-correction for super-flat CRT, Vertical size, Vertical position • Vertical size and position prescales for factory adjustment • Vertical moiré cancellation through vertical ramp waveform • Compensation of vertical breathing with EHT variation; I2C-bus gain adjustment EW section • Symmetrical geometry corrections: Pin cushion, Keystone, Top/Bottom corners separately, S- and W-corrections • Horizontal size adjustment • Tracking of EW waveform with Vertical size and position, horizontal size and frequency • Compensation of horizontal breathing with EHT variation, I2C-bus gain adjustment Dynamic correction section • Generates vertical waveform for dynamic corrections like focus, brightness uniformity, ... • 1 output with vertical dynamic correction waveform, both polarities, tracking with vertical size and position DC/DC controller section • Step-up and step-down conversion modes • External sawtooth configuration •I2C-bus-controlled output voltage • Synchronized on hor. frequency with phase selection • Selectable polarity of drive signal • Protection at H unlock condition DESCRIPTION The STV6889 is a monolithic integrated circuit as- sembled in a 32-pin shrink dual-in-line plastic package. This IC controls all the functions related to horizontal and vertical deflection in multimode or multi-frequency computer display monitors. Combined with other ST components dedicated for CRT monitors (microcontroller, video preampli- fier, video amplifier, OSD controller), the STV6889 allows fully I2C bus-controlled computer display monitors to be built with a reduced number of ex- ternal components.
