1 General description
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 driver circuit for a flyback line output stage, a DC coupled vertical saw-tooth output
stage and an East-West raster correction circuit. All adjustable output parameters are I²C-Bus controlled.
Inputs are HSYNC and VSYNC. The HSYNC signal is the reference for the internal clock
system which includes the=χΝ=and χΟ=control loops.
The RGB processor 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 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. It is mounted in a P-MQFP package with 64 pins.
