CXAF-025000-3-AL-39 from AKER, 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 #1 at the 25.000000 MHz fundamental AT-cut crystal, 3 pF shunt capacitance max, 100 uW max drive level; the drawing gives no signal name. |
| 2 | GND | power_in | Pad #2 is labelled GND on the package drawing and is normally tied to the lid and ground. |
| 3 | XTAL2 | passive | Crystal terminal #3 at the 25.000000 MHz fundamental AT-cut crystal, 50 ohm ESR max; the drawing gives no signal name. |
| 4 | GND | power_in | Pad #4 is labelled GND on the package drawing and is normally tied to the lid and ground. |
