General description
The SDA 9380 is a highly integrated deflection controller and RGB video processor for CTV receiv-
ers with 15 to 19kHz or 31 to 38kHz line frequencies. The deflection component controls among oth-
ers an horizontal drive2001-01-29r 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 inter-
nal clock system which includes the
=
Φ1=
and
Φ2=
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 modula-
tion circuit.
The supply voltages of the IC are 3.3V and 8V. It is mounted in a P-MQFP package with 64 pins.
