3225 12M 18PF 20PPM from SST, 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 connected to the resonator (pin 1 and pin 3 are the X'tal connections, and pin 1 is marked by the corner chamfer on the pad). |
| 2 | GND | power_in | Ground pad, listed with pin 4 as GND in the connection table. |
| 3 | XTAL2 | passive | Crystal terminal connected to the resonator (pin 1 and pin 3 are the X'tal connections, 12.000 MHz, CL 18 pF). |
| 4 | GND | power_in | Ground pad, listed with pin 2 as GND in the connection table. |
