Changjing · Crystals · SMD3225-4P
AD-CJ13-240001210C30 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 connected to one side of the quartz blank, with 12pF load capacitance specified for the 24MHz fundamental-mode resonator. |
| 2 | GND | power_in | Case/ground pad marked GND in the internal view connection, not connected to the quartz blank. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the quartz blank, with 12pF load capacitance specified for the 24MHz fundamental-mode resonator. |
| 4 | GND | power_in | Case/ground pad marked GND in the internal view connection, not connected to the quartz blank. |
