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

ABM8AIG-20.000MHZ-2Z-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 | Crystal | passive | Crystal terminal, one of the two crystal connections; the datasheet gives no electrical limits for this pin. The chamfer may be on pin 1 or pin 4 without affecting crystal electrical characteristics. |
| 2 | GND | power_in | Ground pin, electrically connected to the lid according to the datasheet; the datasheet gives no electrical limits for this pin. |
| 3 | Crystal | passive | Crystal terminal, the second crystal connection; the datasheet gives no electrical limits for this pin. |
| 4 | GND | power_in | Ground pin, electrically connected to the lid according to the datasheet; the chamfer may be on this pin or on pin 1, which does not affect crystal electrical characteristics. |
