Oscillation Circuit
The HD66787 generates oscillation by internal R-C oscillator with an external oscillation resistor placed
between the OSC1 and OSC2 pins. The oscillation frequency varies depending on the value of external
resistor, the distance of wiring, and the power supply voltage for the oscillation. For example, the
oscillation frequency becomes low when increasing the value of Rf resistor, or lowering the power supply
voltage. See the “Electric Characteristics Notes” section for the relationship between the Rf resistor value
and the oscillation frequency.

Note 1) Place the Rf resistor close to the OSC1, OSC2 pins.
Note 2) Make sure not to arrange other wiring beneath or close to OSC1-OSC2 wiring to avoid effects from
coupling.
