EURO QUARTZ 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 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.
