Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions or at any other condition beyond those indicated in the operational sections of this specification is not implied.

The SDA 9380 is a highly integrated deflection controller and RGB video processor for CTV receivers with 15 to 19kHz or 31 to 38kHz line frequencies. The deflection component controls among others an horizontal drive2001-01-29r 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 of SDA 9380 are I²C-Bus controlled. Inputs are HSYNC and VSYNC. The HSYNC signal of SDA 9380 is the reference for the internal clock system which includes the=1=and 2=control loops.

The RGB processor of SDA 9380 has two YUV/RGB inputs and one RGB input. One YUV/RGB input and the RGB input are for SVGA and text/OSD with fast blanking. The RGB output stage of SDA 9380 has two control loops for cut off and white level with halt capability in vertical shrink modes. An overall Y output and an adjustable delay of the RGB outputs related to this signal are suitable for a scan velocity modulation circuit.

The supply voltages of the IC are 3.3V and 8V. SDA 9380 is mounted in a P-MQFP package with 64 pins.
