**CREC** · Crystals · SMD3225-4P

01.X.MD.120JJVF0028636360 from CREC, 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 (pins 1# and 3# connect to the X'tal); pad is the chamfered corner at bottom right of the bottom view. |
| 2 | GND | power_in | Ground connection (pins 2# and 4# are GND), typically tied to the lid/ground. |
| 3 | XTAL2 | passive | Crystal terminal (pins 1# and 3# connect to the X'tal). |
| 4 | GND | power_in | Ground connection (pins 2# and 4# are GND), typically tied to the lid/ground. |
