CJ16-4800011108C30 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 the resonator (IN) for a 48.000MHz fundamental-mode crystal with 11.1pF load capacitance, drive level <100µW. |
| 2 | GND | power_in | Ground pad, not connected to the crystal element in the internal view; connect to ground. |
| 3 | OUT | passive | Crystal terminal connected to the resonator (OUT), the second crystal terminal opposite IN, 35 ohm max resonance resistance. |
| 4 | GND | power_in | Ground pad, not connected to the crystal element in the internal view; connect to ground. |
