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

ABM8-166-114.285MHZ-T2 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; the top-view drawing shows it wired to one side of the quartz blank (114.285 MHz, 3rd overtone AT-cut, CL 18 pF). |
| 2 | NC | unconnected | Pad with no internal connection to the crystal in the top-view drawing; the datasheet gives it no function. |
| 3 | XTAL2 | passive | Crystal terminal; the top-view drawing shows it wired to the opposite side of the quartz blank (114.285 MHz, 3rd overtone AT-cut, CL 18 pF). |
| 4 | NC | unconnected | Pad with no internal connection to the crystal in the top-view drawing; the datasheet gives it no function. |
