PLL-SPLIT VIF/SIF IC
Connecting a tuning coil and capacitor to these pins enables
an oscillation.
The tuning capacitor of about 30pF 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 leakage
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 1pF 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.

The recommended supply voltage is 5V or 9 to 12V.
In the case of 5V supply, it should be tied to pin 17.
In the case of 9 to 12V supply, a regulated output of 5V
are available in pin 17.
An output amplitude is positive 2VP-P in the case of 87.5%
video modulation.
It is ground (GND) for the SIF.
