CJ13-221182010A20 from Changjing, 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 (pad 1, marked with the chamfered pad), connected to the crystal element in the pad-layout drawing; 22.1184MHz fundamental mode, 20pF load capacitance. |
| 2 | NC | unconnected | Pad 2 is not connected to the crystal element in the pad-layout drawing, and the datasheet gives no function for it. |
| 3 | XTAL2 | passive | Crystal terminal 2 (pad 3), connected to the crystal element in the pad-layout drawing; 22.1184MHz fundamental mode, 20pF load capacitance. |
| 4 | NC | unconnected | Pad 4 is not connected to the crystal element in the pad-layout drawing, and the datasheet gives no function for it. |
