11 / 14 page November 1987 11 Philips Semiconductors Product specification Video control combination circuit with automatic cut-off control TDA3507 Notes 1. < 115 mA after warm-up. 2. Values are proportional to the supply voltage. 3. When V11-24 < 0,4 V during clamping time the black levels of the inserted RGB signals are clamped on the black levels of the internal RGB signals. When V11-24 > 0,9 V during clamping time the black levels of the inserted RGB signals are clamped on an internal DC voltage (correct clamping of the external RGB signals is possible only when they are synchronous with the sandcastle pulse). 4. When pins 21, 22 and 23 are not connected, an internal bias voltage of 5,5 V is supplied. 5. Automatic cut-off control measurement occurs in the following lines after start of the vertical blanking pulse: line 12: measurement of leakage current (R + G + B) line 13: measurement of red cut-off current line 14: measurement of green cut-off current line 15: measurement of blue cut-off current 6. Black level of the measured channel is nominal; the other two channels are blanked to ultra-black. 7. All three channels blanked to ultra-black. The cut-off control cycle occurs when the vertical blanking part of the sandcastle pulse contains more than 3 line pulses. The internal blanking continues until the end of the last measured line. The vertical blanking pulse is not allowed to contain more than 34 line pulses, otherwise another control cycle begins. 8. The sandcastle pulse is compared with three internal thresholds (proportional to VP) and the given levels separate the various pulses. 9. Blanked to ultra-black ( −25%). 10. Pulse duration ≥ 3,5 µs. Difference in gain between normal mode and signal insertion mode ∆G1,3,5 −− 10 % Sandcastle pulse detector (pin 10) note 8 Levels for separating the following pulses: horizontal and vertical blanking pulses note 9 V10 1,0 1,5 2,0 V required pulses (H +V) V10 2,1 2,5 2,9 V horizontal pulses V10 3,0 3,5 4,0 V required pulses (H) V10 4,1 4,5 5,0 V clamping pulses note 10 V10 6,5 7,0 7,5 V required pulses V10 7,6 − 12,0 V no keying V10 −− 1,0 V Input current −I10 −− 110 µA PARAMETER CONDITIONS SYMBOL MIN.
