CXAF-032768-3-AL-01 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 for the 32.768 kHz resonator (the datasheet does not label it beyond #1), with 12 pF load capacitance specified. |
| 2 | GND | power_in | Marked #2:GND on the bottom view of the package drawing, to be connected to ground. |
| 3 | XTAL2 | passive | Second crystal terminal of the 32.768 kHz resonator (the datasheet does not label it beyond #3), with 12 pF load capacitance specified. |
| 4 | GND | power_in | Marked #4:GND on the bottom view of the package drawing, to be connected to ground. |
