Description

OP4008B Quartz SAW Stabilized and Filtered Diff Sine Technology Fundamental-Mode Oscillation at 669.327 MHz Voltage Tunable for Phase Lock Loop Operations Optical Timing Reference for Forward Error Correction Applications

The output of this device OP4008B is generated and filtered by narrow-band quartz SAW elements at 669.327 MHz. The con-figuration of this clock OP4008B provides a pure signal for optical timing applications in noisy signal environ-ments. The OP4008B Q/Q differential output swing of ±1 volt about 0 Vdc has symmetry better than ±1% into loads from40 to 70 ohms, dete-rmined 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.
