S322520M20PF10PPM 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 | X1 | passive | Crystal terminal (#1,#3 are the X'tal connections); pin 1 is marked by the chamfered pad corner, and it is interchangeable with pin 3. |
| 2 | GND | power_in | Ground connection (#2,#4 are GND), connected to the package lid/case. |
| 3 | X2 | passive | Crystal terminal (#1,#3 are the X'tal connections), interchangeable with pin 1; 20.000 MHz fundamental, 20 pF load capacitance. |
| 4 | GND | power_in | Ground connection (#2,#4 are GND), connected to the package lid/case. |
