CJ13-080001210B20 from Changjiang Electronics Tech (CJ), 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 8.000MHz quartz blank (12pF load capacitance, fundamental mode); interchangeable with pin 3. |
| 2 | GND | power_in | Ground pad, not connected to the crystal blank, to be tied to ground. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the 8.000MHz quartz blank (12pF load capacitance, fundamental mode); interchangeable with pin 1. |
| 4 | GND | power_in | Ground pad, not connected to the crystal blank, to be tied to ground. |
