**Seiko Epson** · Oscillators · SMD2520-4P

X1G0041710150 from Seiko Epson, in a SMD2520-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ST | input | Standby control: H or open outputs the specified frequency, L sets output to high impedance and stops oscillation (VIH 80 % Vcc min, VIL 20 % Vcc max). |
| 2 | GND | power_in | Ground connection. |
| 3 | OUT | output | CMOS clock output with VOH Vcc-0.4 V min, VOL 0.4 V max, load up to 15 pF max. |
| 4 | VCC | power_in | Supply voltage 1.6 V to 3.6 V; add a 0.01 to 0.1 uF decoupling capacitor between VCC and GND close to the device. |
