2 / 12 page 1996 Jan 09 2 Philips Semiconductors Product specification Video control combination circuit TDA3504 FEATURES • Capacitive coupling of the colour difference and luminance input signals with black level clamping in the input stages • Linear saturation control acting on the colour difference signals • (G−Y) and RGB matrix • Linear transmission of inserted signals • Equal black levels for inserted and matrixed signals • 3 identical channels for the RGB signals • Linear contrast and brightness controls, operating on both the inserted and matrixed RGB signals • Clamping, horizontal and vertical blanking of the three input signals controlled by a 3-level sandcastle pulse • Emitter-follower outputs for driving the RGB output stages. 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. QUICK REFERENCE DATA All voltages referenced to pin 18 (ground). ORDERING INFORMATION SYMBOL PARAMETER MIN. TYP. MAX.
