SM8760CA

SEIKO NPC CORPORATION —6

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

250k

Ω).

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 0.1

µF (approximately) multi-layer ceramic capacitor connected directly alongside the

SM8760CA.

C202 is a 33

µF (approximately) electrolytic capacitor.

Note. This is a sample connection diagram only, and its use is not a guarantee of SM8760CA device characteristics.
