ECS-320-8-37B-7KM-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 (In/Out) on pad 1; datasheet states pads 1 and 3 are interchangeable and the crystal is symmetrical. |
| 2 | Gnd | power_in | Ground pad (Gnd); datasheet pad connection table lists this pad as ground with no further electrical limits stated. |
| 3 | Out/In | passive | Crystal terminal (Out/In) on pad 3; datasheet states pads 1 and 3 are interchangeable and the chamfer on the bottom pad has no electrical significance. |
| 4 | Gnd | power_in | Ground pad (Gnd); datasheet pad connection table lists this pad as ground with no further electrical limits stated. |
