SM8760CA
Typical Connection Circuit
A typical connection circuit diagram is shown in Figure 4.
1) The SM8760CA oscillator circuit between XT and XTN has a built-in feedback resistor (approximately
250kΩ).
2) The oscillator circuit capacitances C101 and C102 connected to XTN and XT, to match the crystal load
capacitor.
3) R201 and R202 are impedance matching resistor for board pattern.
4) C201 and C202 are bypass capacitors inserted between the supply voltage lines.
C201 is a 0.1µF (approximately) multi-layer ceramic capacitor connected directly alongside the
SM8760CA.
C202 is a 33µF (approximately) electrolytic capacitor.
