**Abracon LLC** · Pre-ordered Products · SMD3225-4P

ABM8-16.000MHZ-9-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 on the top-view drawing without a GND label (diagonal to pin 3); the load capacitance is 18.0 pF standard. |
| 2 | GND | power_in | Marked GND on the top-view outline drawing of the 3.2 x 2.5 mm ceramic package. |
| 3 | XTAL2 | passive | Crystal terminal, shown on the top-view drawing without a GND label (diagonal to pin 1); the drive level is 10 to 100 µW. |
| 4 | GND | power_in | Marked GND on the top-view outline drawing of the 3.2 x 2.5 mm ceramic package. |
