CN4048M00012T8188021 from JWT, 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 1 of the 48.000MHz AT-cut resonator, CL 12pF, drive level 1 to 100uW (10uW typical). |
| 2 | GND | power_in | Ground pad, marked GND in the crystal-connection drawing and tied to the lid. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 48.000MHz AT-cut resonator, CL 12pF, resonance resistance 30 ohm max. |
| 4 | GND | power_in | Ground pad, marked GND in the crystal-connection drawing and tied to the lid. |
