X1G0041710018 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 | S̅T̅ | input | Standby control: "H" or OPEN keeps oscillation running and OUT enabled at the specified frequency, "L" stops oscillation and puts OUT in high impedance, with VIH min 80% Vcc, VIL max 20% Vcc, and the level must not exceed the supply voltage. |
| 2 | GND | power_in | Ground terminal at 0 V, the return for the VCC supply and the output. |
| 3 | OUT | output | CMOS clock output, with VOH min 90% Vcc at -4 mA and VOL max 10% Vcc at 4 mA at Vcc = 3.3 V, specified for a CMOS load of 15 pF. |
| 4 | VCC | power_in | Supply voltage from 1.60 V to 3.63 V; a 0.01 µF to 0.1 µF bypass capacitor is recommended between VCC and GND, placed as close to the VCC pin as possible. |
