OP4014B

Preliminary OP4014B Quartz SAW Stabilized and Filtered “Diff Sine” Technology Fundamental-Mode Oscillation at 627.329 MHz Voltage Tunable for Phase Lock Loop Operations Optical Timing Reference for G.709 Timing Applications The output of this device is generated and filtered by narrowband quartz SAW elements at 627.329 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. 627.329 MHz Optical Timing Clock Absolute Maximum Ratings Rating DC Suppy Voltage Tune Voltage Case Temperature Value 0 to 5.5 0 to 6 -55 to 100 Units VDC VDC °C SMC-08 Electrical Characteristics Operating Frequency Characteristic Absolute Frequency Tune Range Tune Voltage Tuning Linearity Tuning Sensitivity Modulation Bandwidth Voltage into 50 Ω (VSWR≤1.2) Sym fO Notes 1, 9 2 1 1, 8 2, 10 1,3 1,3 3, 4, 5 3, 4, 6 3, 4, 6, 7 Minimum ±25 0 ±3% 140 125 0.60 49 300 265 1.1 2:1 51 -30 -60 -70 -100 -120 -150 <1 10 12 1 50 3.13 ppm/V kHz VP-P % dBc dBc dBc/Hz dBc/Hz Typical 627.329 +3 Maximum Units MHz ppm VDC df/dv VO Q and Q Output Operating Load VSWR Symmetry Har...
