ECS-320-8-36CKM-TR
ECS · Crystals · SMD2520-4P
ECS-320-8-36CKM-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 that is electrically interchangeable with pad 3, since the crystal is symmetrical; the datasheet gives no further electrical limits for this pad. |
| 2 | Gnd | power_in | Ground pad, labelled Gnd in the datasheet pad connection table; the datasheet gives no further electrical limits for it. |
| 3 | Out/In | passive | Crystal terminal that is electrically interchangeable with pad 1, since the crystal is symmetrical; the datasheet gives no further electrical limits for this pad. |
| 4 | Gnd | power_in | Ground pad, labelled Gnd in the datasheet pad connection table; the datasheet gives no further electrical limits for it. |
