SJK SHENZHEN CRYSTAL TECH · Crystals · SMD3225-4P

7U27120E20UCG from SJK SHENZHEN CRYSTAL TECH, in a SMD3225-4P. 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 the quartz element in the top-view crystal connection drawing (27.120 MHz, CL 20 pF).
2 GND power_in Lid/ground pad marked GND in the top-view crystal connection drawing, not connected to the crystal element.
3 XTAL2 passive Crystal terminal 2, connected to the quartz element in the top-view crystal connection drawing (27.120 MHz, CL 20 pF).
4 GND power_in Lid/ground pad marked GND in the top-view crystal connection drawing, not connected to the crystal element.
