ECS-300-8-36CKM-TR

ECS · Crystals · SMD2520-4P

ECS-300-8-36CKM-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; the crystal is symmetrical, so pad 1 and pad 3 are interchangeable.
2 Gnd power_in Ground connection for the crystal package.
3 Out/In passive Crystal terminal; the crystal is symmetrical, so pad 3 and pad 1 are interchangeable.
4 Gnd power_in Ground connection for the crystal package.
