Q22FA12800594 from Seiko Epson, in a SMD2016-4P. 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 | X'tal | passive | Crystal terminal connected to one side of the quartz resonator (24.000000 MHz fundamental, CL 9 pF, drive level max 100 µW, recommended 10 µW). |
| 2 | GND | power_in | Connected to the metal cover and should be connected to ground. |
| 3 | X'tal | passive | Crystal terminal connected to the other side of the quartz resonator (24.000000 MHz fundamental, CL 9 pF, drive level max 100 µW, recommended 10 µW). |
| 4 | GND | power_in | Connected to the metal cover and should be connected to ground. |
