Preliminary
• Quartz SAW Frequency Stability
• Fundamental Fixed Frequency
• Very Low Jitter and Power Consumption
• Rugged, Miniature, Surface-Mount Case
• Low-Voltage Power Supply (3.3 VDC)
This digital clock is designed for use in high-speed communications timing systems. Fundamental-mode
oscillation is made possible by surface-acoustic-wave (SAW) technology. The design results in low jitter,
compact size, and low power consumption. Differential outputs provide a sine wave that is capable of driving
50 Ω loads.

subject to change without notice.
4. Only under the nominal conditions of 50 Ω load impedance with VSWR ≤
1.2 and nominal power supply voltage.
5. Symmetry is defined as the pulse width (in percent of total period)
measured at the 50% points of Q or Q. (See: Timing Definitions.)
8. Period jitter measured with a 200 mVP-P sine wave swept from 1 MHz to
one-half of fO at the VCC power supply terminal.
9. The outputs are enabled when Terminal 8 is at logic HIGH. Propagation
delay is defined as the time from the 50% point on the rising edge of
ENABLE to the 90% point on the rising edge of the output amplitude or as
the fall time from the 50% point to the 10% point. (SEE: Timing
Definitions.)
