RF setting frequency,
and the error is outputted
by Charge pump.
LPF for high frequency
rejection is connected to
9 this terminal. The signal
after a high frequency
rejection is amplified with
common-emitter
amplifier, and the voltage
for frequency control
impressed to variable
capacitor is generated.
The reference frequency
is 62.5 kHz.

oscillator.
Toshiba recommends
use of a Clapp oscillator
as external LC
resonance circuit to
reduce effects of IC
parasitic capacitance and
others.
Analog GND
A.VCC
Bypass capacitor pin
used by sound VCO to
reduce bias noise.
The smaller the external
capacitance, the worse
the sound S/N.
