External dimensions
OE pin = "H" or "open": Specified frequency output.
OE pin = "L" : Output is high impedance.
(Unit: mm)
Footprint (Recommended)
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).
