Video Clamp The video clamp circuit employs a sync peak value clamp. Input impedance is at a level of approximately 30 kΩ to reduce compression of the sync pulse. Note that sag is generated in the sync pulse when a capacitor of 0.47 µF or lower is used for C10 at pin 16. White Clip Circuit The white clip level is set to 92.5%. A circuit that produces a sharp white clip is used in order to produce high linearity characteristics for the video. Increasing the white clip frequency characteristic by another 5 MHz eliminates video carrier cutoff by the chroma signal and prevents deterioration of audio buzz characteristics.

Note that using a capacitor lower than 0.22 µF at pin 3 causes an increase in sync pulse sag. The input resistance at pin 11, which is the oscillator input pin, is 3 kΩ. Pins 9 and 10 are oscillator output pins, and are NPN transistor emitter-follower types. The oscillator frequency is selectable by switching the pin 7 channel switch between SAW resonator low channel and high channel. When the channel switch is open, oscillation output is performed from pin 9, while grounding the switch causes output from pin 10. The switching voltage of the channel switch is approximately 2.1 V. When the channel switch is grounded, a current of 30 µA flows through pin 7, which is sufficient to drive an electronic switch. Antenna Switch RF oscillator on/off operation. Opening the switch at pin 13 stops oscillation of the RF oscillator and the antenna switch drive output at pin 14 becomes 0 V. The audio system is operating in this state, which acts to suppress generation of popping noise in the audio as the antenna switches between on and off. When pin 13 is connected to V CC by a closed switch, the RF oscillator is operational and the antenna switch drive output DC level at pin 14 is high. Pin 13 should be connected to V CC when the antenna switch is not used. A maximum current of 30 mA can be obtained from the antenna switch driver. Be sure to connect 10 kΩ for R3 at pin 13 when the antenna switch is being used. R2 is used as protective resistance when the antenna switch power supply is switched on before the chip power supply. The antenna switch links the drive circuit that switches the RF switch on and off with the chip’s 11 10 R2 10 k RF switch SAW resonator 9 14 13 3k 7 VCC 3 RF oscillator + C2 0.22 µ 80 k RF oscillator 60 k Antenna switch driver Channel switch 60 k Figure 3 RF Oscillator Interface Circuit 6 Figure 4 Antenna Switch Interface Circuit HA11560FP/T Audio Modulator Pins 4 and 5 make up the reference oscillator for the 4.5 MHz audio modulator. Pin 4 is the oscillator ’s reference bias source. A 15 pF capacitor must be used for C3 at pin 4 to cut the ac signal. The oscillation frequency is determined by an external tank circuit. An external cuppling capacitor is not required when pin 6, which is the audio input pin, is almost equal to ground potential and the audio input signal dc level is ground potential. The ground potential of the input pin results in a circuit configuration that reduces pin 6 voltage fluctuations and suppresses popping noise.
