SiT5711 Datasheet | Sitime

Description The Si T5711 is the industry’s smallest Stratum 3E OCXO (9 mm x 7 mm) with ±5 ppb over-temp stability and ±0.04 ppb/°C typical frequency slope (d F/d T). Leveraging Si Time’s unique Dual MEMS® and Turbopensation® temperature sensing technology, it delivers excellent stability in the presence of environmental stressors - airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI). The Si T5711’s environmental robustness enables unmatched ease-of-use and reduces system manufacturing overhead: - Highly flexible location on the PCB - Minimal shielding for thermal isolation Si T5711 can be factory-programmed to any frequency between 1 MHz and 60 MHz. The Si T5711 is supported by the Si T6731 evaluation board. 9 mm x 7 mm Package Features - Any frequency between 1 MHz and 60 MHz, in 1 Hz steps - ±0.04 ppb/°C frequency slope typical d F/d T - ±5 ppb frequency stability over temperature - Up to 85°C operating temperature range - 1.4E-11 ADEV at 10 second averaging time - Exceptional dynamic stability under airflow and rapid temperature changes - Excellent Holdover over a wide range of conditions - Integrated regulators for on-chip power-supply noise filtering and excellent PSNR - GR-1244 Stratum 3E pliant - Resistant to shock and vibration - 3.3 V supply voltage - LVCMOS and Clipped Sinewave outputs Applications - 4G/5G radio - Base Stations - Digital Switching - Time and Frequency Measurement - IEEE 1588 - Test and measurement Package Pinout Figure 1.
