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

ABM8W-16.0000MHZ-4-B1U-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, connected across the quartz element to pin 3; the chamfered pad on the drawing marks pad #1, though the note says the chamfer may be on pin 1, 2 or 4. |
| 2 | GND | power_in | Pad labeled #2 GND on the bottom-view drawing, to be connected to ground. |
| 3 | XTAL2 | passive | Crystal terminal, connected across the quartz element to pin 1, with load capacitance 4.0 pF per the part number option 4. |
| 4 | GND | power_in | Pad labeled #4 GND on the bottom-view drawing, to be connected to ground. |
