ECS-160-8-33B-RWY-TR 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; pads 1 and 3 are interchangeable because the crystal is symmetrical, and the chamfer on the bottom pad has no electrical significance. |
| 2 | Gnd | power_in | Ground pad connection as listed in the datasheet pad connections table. |
| 3 | Out/In | passive | Crystal terminal; pads 1 and 3 are interchangeable because the crystal is symmetrical, and the chamfer on the bottom pad has no electrical significance. |
| 4 | Gnd | power_in | Ground pad connection as listed in the datasheet pad connections table. |
