**Abracon LLC** · Crystals · SMD3225-4P

ABM8-28.63636MHZ-12-D4Y-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; the top-view outline drawing does not label it GND, and the datasheet gives no further function. |
| 2 | GND | power_in | Marked GND in the top-view outline drawing (case/ground pad). |
| 3 | XTAL2 | passive | Crystal terminal 2; the top-view outline drawing does not label it GND, and the datasheet gives no further function. |
| 4 | GND | power_in | Marked GND in the top-view outline drawing (case/ground pad). |
