TDA9160
General description
The TDA9160 is an I²C-bus controlled, alignment-free PAL/NTSC/SECAM decoder/processor. The device contains horizontal and vertical drive outputs and an east-west correction drive circuit. The TDA9160 has been designed for use with baseband chrominance delay lines and DC-coupled vertical and east-west output circuits.
The device has three inputs, two for CVBS and one for S-VHS. The main signal is available at the luminance and colour difference outputs and, also, at the TXT output (unprocessed). The signal at the PIP output can be selected independently from the main signal.
The circuit provides a drive pulse for the horizontal output stage, a differential sawtooth current for the vertical output stage and an east-west drive current for the EW output stage. These signals can be used to provide geometry correction of the picture. A two level sandcastle pulse and an HA pulse are made available for synchronization purposes.
The I²C-bus address of the TDA9160 can be programmed by hardware.
