ABM8-27.000MHZ-10-1-U-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 1 on the outline drawing's top view, bottom-left, with no GND label; load capacitance is 18.0 pF standard. |
| 2 | GND | power_in | Pin 2 is labeled GND on the outline drawing top view (bottom-right), tied to the lid/case. |
| 3 | XTAL2 | passive | Crystal terminal 2 on the outline drawing's top view, top-right, with no GND label; it sits diagonally opposite pin 1. |
| 4 | GND | power_in | Pin 4 is labeled GND on the outline drawing top view (top-left), tied to the lid/case. |
