Note.
OE Pin
OE pin = "H" or "open" : Specified frequency output.
OE pin = "L" : Output is high impedance, oscillation stops.
To maintain stable operation, provide by-pass capacitor with
more than 0.1 μF at a location as near as possible to the power
source terminal of the crystal products (between VCC - GND).
