ECS-260-10-36B-CKY-TR

ECS · Pre-ordered Products · SMD2520-4P

ECS-260-10-36B-CKY-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 (In/Out) of the symmetrical 2.5 x 2.0 mm crystal; pads 1 and 3 are interchangeable and the bottom-pad chamfer has no electrical significance.
2 Gnd power_in Ground pad connected to ground, one of the two Gnd pads of the 4-pad crystal package.
3 Out/In passive Crystal terminal (Out/In) of the symmetrical crystal; pads 1 and 3 are interchangeable and the bottom-pad chamfer has no electrical significance.
4 Gnd power_in Ground pad connected to ground, the second of the two Gnd pads of the 4-pad crystal package.
