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.

Internal driving current: 2 mA
