External dimensions


(Unit: mm)

• Active High
OE pin = "H" or "open" : Specified frequency output.
OE pin = "L" : Output is high impedance, oscillation stops.
• Active Low
OE pin = "L" or "open" : Specified frequency output.
OE pin = "H" : Output is high impedance, oscillation stops.

Footprint (Recommended)


(Unit: mm)

To maintain stable operation, provide a 0.01μF 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).
