Oscillation Circuit
The HD66726 can either be supplied with operating pulses externally (external clock mode), oscillate using
an internal R-C oscillator with an external oscillator-resistor (external resistor oscillation mode).
1) External clock mode
2) External resistor oscillation mode

Rf
The oscillator frequency can be
adjusted by oscillator resistor
(Rf). If Rf is increased or power
supply voltage is decreased, the
oscillation frequency decreases.
For the relationship between Rf
resistor value and oscillation
frequency, see the Electric
Characteristics Notes section.
