Description of Operation

The Y, R-Y and B-Y signals input from Pins 1, 2, 3, 21, 22 and 23 are clamped by the clamp circuit and sent to the YUV SW circuit. The Y signal input from Pin 19 is clamped by the clamp circuit and then sent to the Y SW circuit. The YUV SW circuit receives the switching signal from Pin 6 and selects either the signals from Pins 1, 2 and 3 or from Pins 21, 22 and 23. The R-Y and B-Y signals output from the YUV SW circuit are attenuated and sent to the delay line and delay switch circuits. The delay time at the delay line circuit can be set as desired in the range of 500 to 700ns according to the resistance value connected between Pin 15 and GND. After passing through the delay line circuit, the signals are sent to the delay switch circuit where the Pin 13 control voltage is received and delay on/off switching is performed. The signals output from the delay switch circuit are input to the base band hue and color control circuits where the Pins 16 and 17 control voltages are received and hue and color control is performed. Then, the signals are amplified by the drive circuit and output from Pins 9 and

10. The drive circuit gain can be switched between two values according to the voltage applied to Pin 7. Two types of Y signals, 0dB and –6dB with respect to the input level, are output from the YUV SW circuit. The 0dB signal is sent as is to the Y SW circuit, and the –6dB signal is output from Pin 8. The Y SW circuit receives the switching signal from Pin 18 and selects the Pin 19 signal and either the Pin 1 or Pin 23 signal selected by YUV SW. Two types of Y signals, an unadjusted signal and a signal attenuated by –6dB, are output from the Y SW circuit. These signals are sent to the level switch circuit where one of them is selected according to the voltage applied to Pin 7 and output from Pin 12.
