X1G0041710031 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 input: HIGH or OPEN enables oscillation and output at the specified frequency, LOW stops oscillation and sets OUT to high impedance (VIH min 80 % Vcc, VIL max 20 % Vcc). |
| 2 | GND | power_in | Ground terminal (0 V); a 0.01 µF to 0.1 µF bypass capacitor between VCC and GND is recommended. |
| 3 | OUT | output | CMOS output terminal driving up to 15 pF load, high impedance when ST is LOW. |
| 4 | VCC | power_in | Supply voltage terminal, 1.60 V to 3.63 V, with a 0.01 µF to 0.1 µF bypass capacitor placed close to the pin. |
