Changjing · Crystals · SMD2016-4P
CJ16-320001210B20 from Changjing, in a SMD2016-4P. 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 | IN | passive | Crystal terminal connected to one side of the quartz blank (IN) for the 32MHz, 12pF load resonator. |
| 2 | GND | power_in | Ground pad on the bottom-right corner in the bottom view, not connected to the crystal blank in the internal view. |
| 3 | OUT | passive | Crystal terminal connected to the other side of the quartz blank (OUT) for the 32MHz, 12pF load resonator. |
| 4 | GND | power_in | Ground pad on the bottom-left corner in the bottom view, not connected to the crystal blank in the internal view. |
