ECS-300-8-37-CKM-TR from ECS, 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/Out | passive | Crystal terminal that is electrically interchangeable with pad 3; the chamfer on the bottom pad has no electrical significance. |
| 2 | Gnd | power_in | Ground connection for the crystal package. |
| 3 | Out/In | passive | Crystal terminal that is electrically interchangeable with pad 1 (datasheet states pads 1 and 3 are interchangeable). |
| 4 | Gnd | power_in | Ground connection for the crystal package. |
