Q22FA23V00501 from Seiko Epson, in a SMD3225-4P. 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 | X1 | passive | Crystal terminal 1 of the FA-238V (12.000 MHz to 15.999 MHz), connected internally to the crystal element; drive level 200 µW max, recommended 1 µW to 100 µW. |
| 2 | GND | power_in | Connected to the metal lid/case, which the datasheet says to ground. |
| 3 | X2 | passive | Crystal terminal 2 of the FA-238V, connected internally to the crystal element; load capacitance 7 pF to ∞. |
| 4 | GND | power_in | Connected to the metal lid/case, which the datasheet says to ground. |
