ECS-320-8-37B-CKY-TR3

ECS INC INTERNATIONAL · Global Sourcing Parts · SMD2016-4P

ECS-320-8-37B-CKY-TR3 from ECS INC INTERNATIONAL, 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; pads 1 and 3 are interchangeable since the crystal is symmetrical.
2 Gnd power_in Ground pad connected to ground.
3 Out/In passive Crystal terminal; pads 1 and 3 are interchangeable since the crystal is symmetrical.
4 Gnd power_in Ground pad connected to ground.
