General Description
The SDA 9362 is a highly integrated deflection controller for CTV receivers with doubled line and standard or doubled field frequencies. It controls among others an horizontal driver circuit for a flyback line output stage, a DC coupled vertical sawtooth output stage and an East-West raster correction circuit. All adjustable output parameters are Ι2C Bus controlled. Inputs are HSYNC, VSYNC and the line locked clock CLL.
FEATUREs
• Deflection - Protection - 16:9 / 4:3
• Ι2C Bus alignment of all deflection parameters
• All EW-, V- and H-functions (incl. Φ2)
• PW EHT compensation
• PH EHT compensation
• Compensation of H-phase deviation (e.g. caused by white bar)
• Upper/lower EW-corner correction separately adjustable
• V-angle correction: Vertical frequent linear modulation of H-phase
• V-bow correction: Vertical frequent parabolic modulation of H-phase
• Three reduced V-scan modes (75 %, 66 %, 50 % V-size) selectable
• H- and V-blanking time adjustable
• Partial overscan adjustable to hide the cut off control measuring lines in the reduced scan modes
• Stop/start of vertical deflection adjustable to fill out the 16/9 screen with different letterbox formats without annoying overscan
• Dynamic PH EHT-compensation (white bar)
• Self adaptation of V-frequency/number of lines per field between 192 and 680 for each possible line frequency
• Protection against EHT run away (X-rays protection)
• Protection against missing V-deflection (CRT-protection)
• Two digital outputs for general purpose, controlled by Ι2C Bus
• Selectable softstart of the H-output stage
• P-MQFP-44-2 package
• 5 V supply voltage
