This digital clock is designed for use in telecom applications; such as Timing for Terabit Router applications.
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
made to drive 50 Ω loads.

Unless otherwise noted, all specifications include any combination of
load VSWR, VCC, and TA. In addition, Q and Q are terminated into
50 Ω 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 Ω load impedance with
VSWR ≤ 1.2 and nominal power supply voltage.
Symmetry is defined as the pulse width (in percent of total period)
measured at the 50% points of Q or Q. (See: Timing Definitions.)
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 CC 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.)
