Note:
Oscillator Circuit
The S1D13700 features a built-in oscillator circuit, with a resonator connected to the XG and XD pins to
generate oscillation. In addition to the crystal resonator, the feedback resistor Rf, drain resistor Rd, and
oscillation capacitors CG and CD must be externally connected to the chip. The RC time constant needed to
produce stable oscillation varies with the crystal resonator used and condition of the board. Determine the
appropriate RC value through careful evaluation.
Note that the higher the oscillation frequency, the smaller the CG and CD values.
