DESCRIPTION
The STV2162 is an I2C bus controlled Video and Deflexion Processor for 2H-Deflection Television Sets. The IC incorporates also an secondary SMPS (Switch Mode Power Supply) controller with Softstart and Protection facilities.

VIDEO PART
■ USER CONTROL FUNCTIONS : CONTRAST, BRIGHTNESS, SATURATION, COLOR EQUALIZER
■ RGB INPUT WITH FAST-BLANKING FOR ON-SCREEN-DISPLAY / TELETEXT
■ FAST BLANKING INPUT FOR CONTRAST REDUCTION (TRANSPARENT MENU BOX)
■ AVERAGE BEAM LIMITER FUNCTION WITH CONTRAST AND BRIGHTNESS REDUCTION
■ PAL/SECAM OR NTSC MATRIX SWITCHABLE BY BUS
■ AUTOMATIC CUT-OFF LOOP WITH INTEGRATED DIGITAL MEMORY AND LEAKAGE CURRENT COMPENSATION
■ FULL WHITE ADJUSTMENT VIA BUS
■ BUS REPLY FOR TUBE COLD INFORMATION AND CUT-OFF COUNTER STATUS
■ APX (AUTO PIX) : ADAPTIVE CONTRAST CONTROL
■ COLOR MATCHING (IN CONNECTION WITH WHITE STRETCH)
■ APL (AUTO PEDESTAL) = ADAPTIVE BRIGHTNESS
■ WHITE STRETCH
■ VERTICAL AND OVERSIZE BLANKING ACCORDING TO ALL ZOOMS
■ INDEPENDENT RIGHT AND LEFT ADJUSTMENT OF HORIZONTAL OVERSIZE BLANKING

SCANNING PART
■ INTERNAL OR EXTERNAL 27MHz CLOCK
