XOF91 Oscillators
7 x 5mm High Frequency HCMOS Oscillator
125MHz to 320MHz
FEATURES
Industry-standard 7.0 x 5.0mm SMD package
Frequency Range 125MHz to 320.0MHz
High Q crystal and ultra-low jitter multiplier circuit

DESCRIPTION
XOF91 series oscillators are designed to provide very high quality
LVCMOS outputs at frequencies from 125MHz to 320MHz. A high Q
crystal and ultra-low jitter multiplier circuit provide extremely good
performance. An enable/disable function is standard and the
oscillator may also be specified with a power down function.

PAD 1 OPTIONS
DISABLE
ENABLE
POWER DOWN
Output is disabled when enable/disable pad is
taken below 0.3 Vcc referenced to ground
Oscillator is continues to run.
Oscillator is enable when enable/disable Pad is
taken above 0.7 Vcc referenced to ground.
Available by special request: Oscillator shuts down
when disabled.
