ECS-480-8-36-RWN-TR from ECS, in a SMD2520-4P. 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 labelled In/Out; the crystal is symmetrical and pads 1 and 3 are interchangeable, so either can be the input or output. |
| 2 | Gnd | power_in | Ground pad (Gnd) of the crystal; the datasheet gives no electrical limit for this pad beyond its ground connection. |
| 3 | Out/In | passive | Crystal terminal labelled Out/In; it is interchangeable with pad 1 because the crystal is symmetrical. |
| 4 | Gnd | power_in | Ground pad (Gnd) of the crystal; the datasheet gives no electrical limit for this pad beyond its ground connection. |
