DESCRIPTION
XOW91 series oscillators are designed to provide a high quality
HCMOS output at high frequencies from 125MHz to 800MHz. Phase
and RMS period jitter are kept within low limits. An enable/disable
function is standard and the oscillator may also be specified with a
power down function.

TRISTATE FUNCTION
DISABLE
Output is disabled when Pad 1 is taken below
0.3 Vcc referenced to ground
Oscillator continues to run while disabled.
Oscillator is enabled when Pad 1 is taken above
0.7 Vcc referenced to ground.
Available by special request: Oscillator shuts
down when disabled. Longer time to enable.
