CM4024M57612T8188131

JWT · Crystals · SMD2520-4P

CM4024M57612T8188131 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 (24.576 MHz, CL 12 pF), connected diagonally across the crystal element to pin 3; the two are interchangeable.
2 GND power_in Ground pin, marked GND in the Top View Crystal Connection drawing, usually tied to the lid/ground.
3 XTAL2 passive Crystal terminal 2 (24.576 MHz, CL 12 pF), connected diagonally across the crystal element to pin 1.
4 GND power_in Ground pin, marked GND in the Top View Crystal Connection drawing, usually tied to the lid/ground.
