ABM8-20.000MHZ-10-B1U-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, shown without a GND label in the top view; the chamfer marking may fall on pin 1, 3 or 4 with no effect on electrical performance. |
| 2 | GND | power_in | Ground pad, labeled GND in the top view of the outline drawing. |
| 3 | XTAL2 | passive | Crystal terminal, shown without a GND label in the top view; the chamfer marking may fall on pin 1, 3 or 4 with no effect on electrical performance. |
| 4 | GND | power_in | Ground pad, labeled GND in the top view of the outline drawing. |
