GENERAL DESCRIPTION
TDA3505 TDA3506
The TDA3505 and TDA3506 are monolithic integrated circuits which perform video control functions in a PAL/SECAM decoder. The TDA3505 is for negative colour difference signals −(R-Y), −(B-Y) and the TDA3506 is for positive colour difference signals +(R-Y), +(B-Y). The required input signals are: luminance and colour difference (negative or positive) and a 3-level sandcastle pulse for control purposes. Linear RGB signals can be inserted from an external source.
