Seiko Epson · Crystals · SMD3225-4P

Q22FA23V0028500 from Seiko Epson, 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 X1 passive Crystal terminal 1 of the FA-238V 3.2 x 2.5 mm unit, connected internally to the crystal element (TOP VIEW internal connection).
2 GND_CASE power_in Connected internally to the metal lid/case; the datasheet says to connect it to ground.
3 X2 passive Crystal terminal 2 of the FA-238V 3.2 x 2.5 mm unit, connected internally to the crystal element (TOP VIEW internal connection).
4 GND_CASE power_in Connected internally to the metal lid/case; the datasheet says to connect it to ground.
