Tri-State Function in Crystal Oscillators

In oscillator with Tri-state function, oscillator output can be controlled by the Tri-state pin as follows: Logic High : Output Enable ; Logic Low : Output Disable.

The Tri-state function would allow output pin to assume high-impedance state, effectively removing the oscillator output from the circuit. Oscillator circuits can remain on or be turned off while output is disabled in Tri-State…
