NXP Semiconductors TDA9141
The TDA9141 is an I2C-bus controlled, alignment-free PAL/NTSC/SECAM decoder/sync processor. The TDA9141 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 comb filter. The IC can process CVBS signals and Y/C input signals.| Part No. | TDA9141 |

GENERAL DESCRIPTION
TDA9141 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.
