Pin 5, Pin 6 (VCO COIL)  
Connecting a tuning coil and capacitor to these pins enables  
an oscillation.  
The tuning capacitor of about 30 pF is recommended.  
The oscillation frequency is tuned in f0.  
In the actual adjustment, the coil is tuned so that the AFT  
voltage is reached to VCC/2 with f0 as an input.  
The printed pattern around these pins should be designed  
carefully to prevent an pull-in error of VCO, caused by the  
laekage interference from the large signal level oscillator to  
adjacent pins.

The interconnection should be designed as short as possible.  
In case the printed pattern has the interference problem, a  
capacitor of about 1 pF is connected between pin 5 or 6 and  
GND so as to cancel the interference and keep enough pull-  
in range even in a weak electric field.  
Pin 7 (VCC)  
VCC  
The recommended supply voltage is 5 V or 9 to 12 V.  
In the case of 5 V supply, it should be tied to pin 17.  
In the case of 9 to 12 V supply, a regulated output of 5 V are  
available in pin 17.

Pin 8 (VIDEO OUT)  
An output amplitude is positive 2 VP-P in the case of 87.5%  
video modulation.
