Changjing · Crystals · SMD2016-4P
CJ16-250000810A20 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 | XTAL1 | passive | Crystal terminal connected to one side of the resonator element in the connection diagram, for 25MHz fundamental mode with 8pF load capacitance. |
| 2 | GND | power_in | Ground pad, labeled GND in the connection diagram (case/lid ground). |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the resonator element in the connection diagram, for 25MHz fundamental mode with 8pF load capacitance. |
| 4 | GND | power_in | Ground pad, labeled GND in the connection diagram (case/lid ground). |
