NX2016SA-48M-EXS00A-CS05517 from NDK, 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 48.000 MHz fundamental-mode unit, with 7 pF typical load capacitance (CL) and 10 µW typical drive level (200 µW max). |
| 2 | GND | power_in | Terminal #2 is connected to the cover and the datasheet says to connect it to GND. |
| 3 | XTAL2 | passive | Crystal terminal #3 of the 48.000 MHz fundamental-mode unit, with 7 pF typical load capacitance (CL) and 40 Ω max ESR. |
| 4 | GND | power_in | Terminal #4 is connected to the cover and the datasheet says to connect it to GND. |
