... December 1992 GENERAL DESCRIPTION The TDA9141 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. ...
