ECS-320-8-37CKM

ECS · Crystals · SMD2016-4P

ECS-320-8-37CKM from ECS, in a SMD2016-4P. 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); 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 as given in the datasheet pad connection table (Gnd).
3 Out/In passive Crystal terminal (labelled Out/In); 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 as given in the datasheet pad connection table (Gnd).
