JWT · Crystals · SMD2520-4P

CM4040M00012 from JWT, 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 XTAL1 passive Crystal terminal 1, connected to one side of the crystal element (diagonal to pin 3) per the top-view crystal connection drawing.
2 GND power_in Marked GND in the top-view crystal connection drawing; not connected to the crystal element.
3 XTAL2 passive Crystal terminal 2, connected to the other side of the crystal element (diagonal to pin 1) per the top-view crystal connection drawing.
4 GND power_in Marked GND in the top-view crystal connection drawing; not connected to the crystal element.
