huaxindianzi · Crystals · SMD3225-4P

CF4027M12010001 from huaxindianzi, 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 connected to one side of the 27.120 MHz AT-cut fundamental crystal blank (CL 10 pF, drive level 300 µW typ, 350 µW max).
2 GND power_in Ground pad, labelled GND in the crystal connection drawing (lid/case ground).
3 XTAL2 passive Crystal terminal connected to the other side of the 27.120 MHz AT-cut fundamental crystal blank (CL 10 pF, drive level 300 µW typ, 350 µW max).
4 GND power_in Ground pad, labelled GND in the crystal connection drawing (lid/case ground).
