Changjing · Crystals · SMD3225-4P

CJ13-250001210A20 from Changjing, 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 (chamfered index pad) connected to one side of the 25MHz, 12pF load, fundamental-mode resonator in the pad-layout drawing.
2 NC unconnected Pad 2 is not connected to the resonator symbol in the pad-layout drawing and has no function stated.
3 XTAL2 passive Crystal terminal 2 connected to the other side of the 25MHz, 12pF load, fundamental-mode resonator in the pad-layout drawing.
4 NC unconnected Pad 4 is not connected to the resonator symbol in the pad-layout drawing and has no function stated.
