ECS-320-8-36B2-CKY-TR from ECS INTERNATIONAL INC, 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, interchangeable with pad 3 because the crystal is symmetrical; the datasheet states no electrical limits for this pad. |
| 2 | Gnd | power_in | Ground pad connection as listed in the datasheet's pad connections; the datasheet states no electrical limits for this pad. |
| 3 | Out/In | passive | Crystal terminal, interchangeable with pad 1 because the crystal is symmetrical; the datasheet states no electrical limits for this pad. |
| 4 | Gnd | power_in | Ground pad connection as listed in the datasheet's pad connections; the datasheet states no electrical limits for this pad. |
