SIT5156AICFD-33E0-10.949297

Oscillators Overview

The SiTime SIT5156AICFD-33E0-10.949297 is a MEMS Super-TCXO from the Elite Platform™ series, operating at a nominal frequency of 10.949297 MHz. It features a clipped sine wave output and supports an enable/disable function. The device operates on a 3.3V supply voltage with a frequency stability of ±2.5 ppm across a temperature range of -40°C to +85°C. Packaged in a 10-SMD, No Lead (CQFN) footprint measuring 5.00mm x 3.20mm x 1.06mm, it utilizes DualMEMS™ and TurboCompensation™ technologies for superior dynamic performance against environmental stressors.

Oscillators Feature Summary

• Integrates DualMEMS™ temperature sensing and TurboCompensation™ technologies for enhanced timing stability under environmental stressors such as vibration, shock, and air flow.
• Includes multiple on-chip regulators to filter power supply noise, eliminating the requirement for external low-dropout (LDO) linear regulators.
• Provides an enable/disable control function to manage power consumption during inactive periods.

Oscillators Applications

• High reliability telecommunications infrastructure
• Precision Global Navigation Satellite Systems (GNSS)
• Industrial automation and control systems
• Wireless networking equipment

Oscillators Procurement Notes

Verify that the specific suffix matches the required frequency and tolerance specifications. Confirm the package type corresponds to the 10-SMD No Lead form factor. Ensure the operating temperature range aligns with the application environment requirements. Check for RoHS compliance status if restricted substances are a concern. Validate the enable/disable pin configuration against the system design.

Oscillators Selection Notes

Select this component when high dynamic stability is critical in environments with significant thermal or mechanical fluctuations. The integrated power regulation simplifies board layout by removing the need for external filtering components. Consider the clipped sine wave output compatibility with downstream logic interfaces. Evaluate the ±2.5 ppm stability against stricter oscillator requirements where lower drift may be necessary.
