• Quartz SAW Stabilized and Filtered “Diff Sine” Technology

• Fundamental-Mode Oscillation at 719.734 MHz

• Voltage Tunable for Phase Lock Loop Operations

• Optical Timing Reference for Forward Error Correction Applications

The output of this device is generated and filtered by narrowband quartz SAW elements at 719.734 MHz. The

configuration of this clock is intended to provide a pure signal for optical timing applications in noisy signal

environments. The Q/Qbar differential output swing of ±1 volt about 0 vdc has symmetry better than ±1% into

loads from 40 ohms 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.
