The output of this device is generated and filtered by narrow-band quartz SAW elements at 669.327 MHz.
The configuration of this clock provides a pure signal for optical timing applications in noisy signal
environments. The Q/Q differential output swing of ±1 volt about 0 Vdc has symmetry better than ±1% into
loads from 40 to 70 ohms, determined by customer application. The long term frequency accuracy is set by
an external reference source allowing this device to complete a Phase Lock Loop design without the usual
noise and jitter problems associated with PLL’s.
