FEATURES

OUTLINE & DIMENSIONS

XOF91 Oscillators

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.

Frequency Range:

125.0MHz to 200.0MHz (15pF load)

125.0MHz to 320.0MHz (10pF load)

Output Logic:

LVCMOS

Integrated Phase Jitter:

0.4ps typical 0.5ps max

(12kHz ~ 20MHz) at 155.520MHz

Period Jitter RMS:

3ps typical, 5 ps max. at 155.520MHz

Period Jitter Peak to Peak:

20ps typ., 30ps max. at 155.520MHz

Frequency Stability
