ECS-163.84-18-33-JGN-TR3 from ECS, 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 | In/Out | passive | Crystal terminal (In/Out) that is electrically interchangeable with pad 3; the datasheet notes pads 1 and 3 are interchangeable and that the bottom chamfer on pad 4 or pad 1 has no electrical significance. |
| 2 | Gnd | power_in | Ground connection for the crystal package. |
| 3 | Out/In | passive | Crystal terminal (Out/In) that is electrically interchangeable with pad 1; the datasheet states the crystal is symmetrical. |
| 4 | Gnd | power_in | Ground connection for the crystal package; the bottom chamfer may be located on this pad with no electrical significance. |
