7 x 5mm High Frequency HCMOS Oscillator
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
Supply voltage 2.5 Volts or 3.3 Volts
Tristate function to conserve power
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.
