ABM81-27.120MHZ-10-B1U-T3 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 1 of the 3.2 x 2.5 mm ceramic package; the datasheet shows it unlabeled in the top view, and the chamfer marker may sit on pin 1, 3 or 4 without affecting electrical performance. |
| 2 | GND | power_in | Labeled GND in the top-view drawing (lid/ground connection) of the ABM8 ceramic SMD crystal. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the ceramic package; the datasheet shows it unlabeled in the top view, and the chamfer marker may sit on pin 1, 3 or 4 without affecting electrical performance. |
| 4 | GND | power_in | Labeled GND in the top-view drawing (lid/ground connection) of the ABM8 ceramic SMD crystal. |
