PLL-SPLIT VIF/SIF IC
In both the split and intercarrier system, the carrier signal
to SIF provided from pin 15 through an emitter follower.

The recommended supply voltage is 5V or 9 to 12V.
In the case of 5V supply, these pins should be tied to pin 20
and pin 21.
In the case of 9 to 12V supply, a regulated output of 5V
are available in pin 20 and 21.

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 also should be designed as short as possible.

It is a regulated 5V output which has current drive
capability of approximately 15mA.
