JWT · Crystals · SMD2520-4P

CM4020M00015T8188125 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 connected to one electrode of the 20.000 MHz resonator (load capacitance 15 pF), interchangeable with pin 3.
2 GND power_in Ground pin, marked GND in the crystal connection drawing (lid/case ground).
3 XTAL2 passive Crystal terminal connected to the other electrode of the 20.000 MHz resonator (load capacitance 15 pF), interchangeable with pin 1.
4 GND power_in Ground pin, marked GND in the crystal connection drawing (lid/case ground).
