ABM8G-25.000MHz-18-D2Y-T from Abracon LLC, 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, marked pin 1 at the bottom left of the top view, which has no polarity marking in the datasheet. |
| 2 | GND | power_in | Marked GND in the top view of the outline drawing, at the bottom right. |
| 3 | XTAL2 | passive | Crystal terminal diagonal from pin 1, at the top right of the top view. |
| 4 | GND | power_in | Marked GND in the top view of the outline drawing, at the top left, and the chamfer may be on this pin without affecting electrical characteristics. |
