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

ABM8W-25.0000MHZ-4-D1X-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 (chamfered pad in the bottom view, though the chamfer may be on pin 1, 2 or 4 depending on material availability), connects to the load capacitor network; 4.0 pF load capacitance for this option. |
| 2 | GND | power_in | Ground pad, marked '#2 GND' on the bottom view of the mechanical drawing. |
| 3 | XTAL2 | passive | Crystal terminal 2, the second crystal connection, diagonal to pin 1 and connected to the load capacitor network. |
| 4 | GND | power_in | Ground pad, marked '#4 GND' on the bottom view of the mechanical drawing. |
