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) .  \nThe 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. RGB output signals are available for driving the video output stages. The circuits provide automatic cut-off control of the picture tube.  \nFeatures  \n• Capacitive coupling of the colour difference and luminance input signals with black level clamping in the input stages  \n• Linear saturation control acting on the colour difference signals  \n• (G-Y) and RGB matrix  \n• Linear transmission of inserted signals  \n• Equal black levels for inserted and matrixed signals  \n• 3 identical channels for the RGB signals  \n• Linear contrast and brightness controls, operating on both the inserted and matrixed RGB signals  \n• Peak beam current limiting input  \n• Clamping, horizontal and vertical blanking of the three input signals controlled by a 3-level sandcastle pulse  \n• 3 DC gain controls for the RGB output signals (white point adjustment)  \n• Emitter-follower outputs for driving the RGB output stages  \n• Input for automatic cut-off control with compensation for leakage current of the picture tube  \nQUICK REFERENCE DATA  \n\n| PARAMETER | CONDITIONS | SYMBOL | MIN. | TYP. | MAX. | UNIT |\n| --- | --- | --- | --- | --- | --- | --- |\n| Supply voltage (pin 6) |  | VP = V6-24 | − | 12 | − | V |\n| Supply current |  | IP = I6 | − | 95 | − | mA |\n| Composite video input |  |  |  |  |  |  |\n| signal (peak-to-peak value) |  | V 15-24(p-p) | − | 0,45 | − | V |\n| Colour difference input |  |  |  |  |  |  |\n| signals (peak-to-peak value) |  |  |  |  |  |  |\n| −(B-Y) or +(B-Y) respectively |  | V 18-24(p-p) | − | 1,33 | − | V |\n| −(R-Y) or +(R-Y) respectively |  | V 17-24(p-p) | − | 1,05 | − | V |\n| Inserted RGB signals |  |  |  |  |  | V |\n| (black-to-white value) |  | V 12,13,14-24 | − | 1,0 | − | V |\n| Three-level sandcastle pulse |  | V 10-24 | − | 2,5 | − | V |\n|  |  |  | − | 4,5 | − | V |\n|  |  |  | − | 8,0 | − | V |\n| Control voltage ranges |  |  |  |  |  |  |\n| brightness |  | V20-24 | 1,0 | − | 3,0 | V |\n| contrast |  | V 19-24 | 2,0 | − | 4,3 | V |\n| saturation |  | V 16-24 | 2,0 | − | 4,3 | V |\n\nPACKAGE OUTLINE  \n28-lead DIL; plastic (SOT117); SOT117-1; 1996 November 20.  \nNovember 1987 2  \nVideo control combination circuit with automatic cut-off control  \nTDA3505  \nTDA3506  \nNote Colour difference inputs are negative for T DA3505 or positive for T DA3506.  \nF ig . 1 Part of block diagram; continued in F ig . 2  \nNovember 1987 3  \nVideo control combination circuit with automatic cut-off control  \nTDA3505  \nTDA3506  \nFig .2 Part of block diagram; continued from F ig . 1  \nNovember 1987 4  \nVideo control combination circuit with automatic cut-off control  \nTDA3505  \nTDA3506  \nPINNING  \nPIN DESCRIPTION  \n1 red output  \n2 green storage capacitor for cut-off control  \n3 green output  \n4 blue storage capacitor for cut-off control  \n5 blue output  \n6 positive supply voltage (+ 12 V)  \n7 blue storage for brightness  \n8 green storage for brightness  \n9 red storage for brightness  \n10 sandcastle pulse input  \n11 fast switch for RGB inputs  \n12 blue input (external signal)  \n13 green input (external signal)  \n14 red input (external signal)  \n15 luminance input  \n16 saturation control input  \n17 colour difference input − (R-Y) or + (R-Y) respectively  \n18 colour difference input − (B-Y) or + (","cbCaiaQ23fXHfYUV","https://ap.wps.com/l/cbCaiaQ23fXHfYUV","pdf",141286,15,"English","# General description\n## Features\n## Quick reference data\n## Package outline\n## Pinning\n## Ratings\n## Characteristics","[{\"question\":\"What are TDA3505 and TDA3506 used for in a PAL/SECAM decoder?\",\"answer\":\"They perform video control functions, processing luminance and colour difference signals and generating RGB output signals for video output stages.\"},{\"question\":\"How do the input colour difference signals differ between TDA3505 and TDA3506?\",\"answer\":\"TDA3505 uses negative colour difference signals -(R-Y) and -(B-Y), while TDA3506 uses positive colour difference signals +(R-Y) and +(B-Y).\"},{\"question\":\"What controls the clamping and blanking of the input signals?\",\"answer\":\"A 3-level sandcastle pulse is used to control clamping, horizontal and vertical blanking of the three input signals.\"}]","TDA3505 - Video control combination circuit with automatic cut-off control | PDF",1791804294,38]
