OP4011B

Preliminary OP4011B 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. 719.734 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 Characteristic Operating Frequency Absolute Frequency Tune Range Tune Voltage Tuning Linearity Modulation Bandwidth Q and Q Output Voltage into 50 Ω (VSWR≤1.2) Operating Load VSWR Symmetry Harmonic Spurious Nonharmonic Spurious Phase Noise dBc/Hz@100Hz offset 1kHz offset 10k offset Noise Floor Q and Q Jitter RMS Jitter No Noise on VCC 200 mVP-P from 1MHz to ½ fO on Output DC Resistance (between Q & Q) DC Power Supply Operating Voltage Operating Current Opera...
