Description

The TDA3504 is an integrated circuit which performs video control functions in a PAL/SECAM decoder for negative colour difference signals -(R-Y) and -(B-Y).

The required input signals of the TDA3504 are luminance and colour difference and a 3-level sandcastle pulse for control purposes. Linear RGB signals can be inserted from an external source. RGB output signals are available for driving the video output stages.
