TDA9143
The TDA9143 is an I2C-bus controlled, alignment-free PAL/NTSC/SECAM decoder/sync processor with blanking facilities for PALplus and EDTV-2 signals. The TDA9143 has been designed for use with baseband chrominance delay lines, and has a combined subcarrier frequency/comb filter enable signal for communication with a PAL/NTSC comb filter. The IC can process both CVBS input signals and Y/C input signals. The input signal is available on an output pin, in the event of a Y/C signal, it is added into a CVBS signal. The sync processor provides a two-level sandcastle, a horizontal pulse (CLP or HA pulse, bus selectable) and a vertical (VA) pulse. When the HA pulse is selected, a line-locked clock (LLC) signal is available at the output port pin (6.75 MHz or 6.875 MHz). A fast switch can select either the internal Y signal with the UV input signals, or YUV signals made of the RGB input signals. The RGB input signals can be clamped with either the internal or an external clamping signal. Two pins with an input/output port and an output port of the I2C-bus are available. The I2C-bus address of the TDA9143 is hardware programmable.
