CF4025M00020 from JWT, 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 | XTAL1 | passive | Crystal terminal (pad with the notched corner marking pin 1) connected to one side of the 25.000MHz AT-cut crystal, load capacitance 20pF. |
| 2 | GND | power_in | Ground/lid-connected pad, labelled GND in the crystal connection drawing, not connected to the crystal element. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the 25.000MHz AT-cut crystal, load capacitance 20pF. |
| 4 | GND | power_in | Ground/lid-connected pad, not connected to the crystal element, to be tied to ground. |
