External dimensions

(Unit: mm)

ST pin = HIGH or "open" : Specified frequency output.
ST pin = LOW : Output is high impedance, oscillation stops.

Footprint (Recommended)


(Unit: mm)

To maintain stable operation, provide a 0.01uF to 0.1uF by-pass capacitor at a location as near as possible to the power source terminal of the crystal product (between Vcc - GND).
