ABM8-20.000MHZ-B3Y-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 (unmarked in the top view); the chamfer marker may sit on pin 1, 3 or 4 with no electrical impact. |
| 2 | GND | power_in | Labelled GND in the top view of the outline drawing (connected to the lid/case). |
| 3 | XTAL2 | passive | Crystal terminal 2 (unmarked in the top view); the chamfer marker may sit on pin 1, 3 or 4 with no electrical impact. |
| 4 | GND | power_in | Labelled GND in the top view of the outline drawing (connected to the lid/case). |
