SiT5711 1 to 60 MHz Emerald Platform Stratum 3E OCXO Description Features The SiT5711 is the industrys smallest Stratum 3E OCXO Any frequency between 1 MHz and 60 MHz, in 1 Hz (9 mm x 7 mm) with 5 ppb over-temp stability and steps 0.04 ppb/C typical frequency slope (dF/dT). Leveraging 0.04 ppb/C frequency slope typical dF/dT SiTimes unique DualMEMS and TurboCompensation 5 ppb frequency stability over temperature temperature sensing technology, it delivers excellent Up to 85C operating temperature range stability in the presence of environmental stressors 1.4E-11 ADEV at 10 second averaging time airflow, temperature perturbation, vibration, shock, and Exceptional dynamic stability under airflow and rapid electromagnetic interference (EMI). temperature changes The SiT5711s environmental robustness enables Excellent Holdover over a wide range of conditions unmatched ease-of-use and reduces system manufacturing Integrated regulators for on-chip power-supply noise overhead: filtering and excellent PSNR GR-1244 Stratum 3E compliant Highly flexible location on the PCB Resistant to shock and vibration Minimal shielding for thermal isolation 3.3 V supply voltage LVCMOS and Clipped Sinewave outputs SiT5711 can be factory-programmed to any frequency between 1 MHz and 60 MHz. The SiT5711 is supported Applications by the SiT6731 evaluation board. 4G/5G radio Base Stations Digital Switching Time and Frequency Measurement IEEE 1588 Test and measurement 9 mm x 7 mm Package Package Pinout VDD 10 1 OE/NC NF 9 2 NF NF 8 3 NF DNC 7 4 NF CLK 6 5 GND Figure 2.
