ENABLE / DISABLE FUNCTION

PIN #1 (E/D CONTROL)

PIN #3 (OUTPUT)

high “1” (V

active (see note)

low “0” (V

high impedance

stop function:

– oscillator stops

– output high impedance

NOTE

– e/d control pin has weak internal pull-up, use external pull-up to ensure

TCXO activation

– for best supply noise rejection, connect a capacitor closely to the supply

voltage pins

– a separate voltage supply rail ensures best phase noise
