2.3.3.240001279 from MDH, in a SMD3225-4P. 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 the quartz blank for the 24.000000 MHz fundamental-mode resonator with 12 pF load capacitance. |
| 2 | GND | power_in | Ground pad, labelled GND in the internal view connection drawing, connected to the lid/case. |
| 3 | XTAL2 | passive | Second crystal terminal connected to the quartz blank, diagonal to pin 1, for the 24.000000 MHz resonator. |
| 4 | GND | power_in | Ground pad, labelled GND in the internal view connection drawing, connected to the lid/case. |
