SJK SHENZHEN CRYSTAL TECH · Crystals · SMD3225-4P

7U22800E20UCG 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 one side of the 22.800000 MHz AT-cut fundamental crystal (CL 20 pF, ESR 60 ohm max); pin 1 is marked by the chamfered pad.
2 GND power_in Ground pin, tied to ground (lid/case) per the top-view crystal connection drawing.
3 XTAL2 passive Crystal terminal 2, connected to the other side of the 22.800000 MHz AT-cut fundamental crystal (CL 20 pF, ESR 60 ohm max).
4 GND power_in Ground pin, tied to ground (lid/case) per the top-view crystal connection drawing.
