GENERAL 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 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.
