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 with high-speed CPUs and communication equipment. Fundamental-
mode oscillation is made possible by surface-acoustic-wave (SAW) technology. The design results in low jit-
ter, compact size, and low power consumption. Differential outputs provide a sine wave that is capable of
driving 50

NOTES:
1.
Unless otherwise noted, all specifications include any combination of load
VSWR, VCC, and TA. In addition, Q and Q are terminated into 50
鈩?/div>
loads to
ground. (See: Typical Test Circuit.)
One or more of the following United States patents apply: 4,616,197; 4,670,681;
4,760,352.
The design, manufacturing process, and specifications of this device are subject
to change without notice.
Only under the nominal conditions of 50

Symmetry is defined as the pulse width (in percent of total period) measured at
the 50% points of Q or Q. (See: Timing Definitions.)
6.
Jitter and other spurious outputs induced by externally generated electrical noise
on V
CC
or mechanical vibration are not included. Dedicated external voltage
regulation and careful PCB layout are recommended for optimum performance.
Applies to period jitter of Q and Q. Measurements are made with the Tektronix
CSA803 signal analyzer with at least 1000 samples.
Period jitter measured with a 200 mV
P-P
sine wave swept from 1 MHz to one-half
of f
O
at the V

power supply terminal.
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.)
