**TXC Corp** · Crystals · SMD3225-4P

7M25000083 from TXC Corp, 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 (marked pin 1, bottom-left corner in bottom view); the datasheet does not name it beyond the pad number, and it connects to the crystal element in the internal view. |
| 2 | GND | power_in | Ground pad, labeled GND in the internal view connection drawing. |
| 3 | XTAL2 | passive | Crystal terminal 2 (pad 3, diagonal to pad 1); the datasheet does not name it beyond the pad number, and it connects to the crystal element in the internal view. |
| 4 | GND | power_in | Ground pad, labeled GND in the internal view connection drawing. |
