Note:
OE pin = "HIGH" or "Open" : Specified frequency output.
OE pin = "LOW" : Output is high impedance.

Footprint (Recommended)

(Unit: mm)

In order to achieve optimum jitter performance,
it is recommended that the capacitor (0.1 µF + 10 µF)
between Vcc and GND pin should be placed as close
to the Vcc pin as possible.
