X1G0041710029 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: a HIGH or OPEN level gives oscillation at the specified frequency with output enabled, while a LOW level stops oscillation and puts OUT in high impedance; ST̅ must not exceed the supply voltage, with VIH at least 80 % Vcc, VIL at most 20 % Vcc, and output enable/disable times of 3 ms max and 100 ns max. |
| 2 | GND | power_in | Ground terminal; the datasheet specifies VCC 1.60 V to 3.63 V with GND at 0 V, and recommends a 0.01 µF to 0.1 µF bypass capacitor between VCC and GND placed as close to the VCC pin as possible. |
| 3 | OUT | output | CMOS clock output that is enabled while ST̅ is HIGH or OPEN and goes high impedance when ST̅ is LOW, with 15 pF maximum CMOS load and rise/fall times of 3.5 ns max. |
| 4 | VCC | power_in | Supply voltage input, specified from 1.60 V to 3.63 V, with a 0.01 µF to 0.1 µF bypass capacitor recommended close to this pin. |
