Function and Description
–
Input pin for I signal. The input
impedance is about 180 kΩ.
–
Input pin for Ib signal. The input
impedance is about 180 kΩ. Single
ended input is also possible. In the
case of single ended input, input only
the DC voltage of Vcc/2.

Ground pin for the VCO block. Form
as wide a ground pattern as possible
to minimize its impedance.
Emitter pin for oscillator. Ground with
an external pull-down resistor. It can
be oscillated by performing feedback
with a resonance circuit mounted
externally between this pin and Pin 11.
Base pin for oscillator. It can be
oscillated by performing feedback with
a resonance circuit mounted externally
between this pin and Pin 10.
Collector pin for oscillator. Open
collector.
Note The pin voltage is measured on Vcc=3.0 V.
