Changjing · Crystals · SMD3225-4P
CJ13-080001210A20 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 marked with the chamfered corner), shown in the suggested pad layout as connected to the crystal symbol for the 8.000MHz, 12pF load resonator. |
| 2 | NC | unconnected | Pad 2 is not connected to the crystal symbol in the suggested pad layout, and the datasheet gives no function for it. |
| 3 | XTAL2 | passive | Crystal terminal 2, shown in the suggested pad layout as connected to the crystal symbol for the 8.000MHz, 12pF load resonator. |
| 4 | NC | unconnected | Pad 4 is not connected to the crystal symbol in the suggested pad layout, and the datasheet gives no function for it. |
