SIT3372AC-4E9-30NX61.440000

Oscillators Overview

The SiTime SIT3372AC-4E9-30NX61.440000 is a differential MEMS VCXO operating at 61.44 MHz with ±35 ppm stability. It features HCSL output signaling and operates on a 3.3 V supply within the -40°C to +85°C temperature range. The device utilizes DualMEMS technology for dynamic performance against shock, vibration, and thermal gradients. Integrated on-chip regulators filter power supply noise, eliminating the need for external LDOs. Factory programmability allows optimization of clock configurations without custom quartz lead times.

Oscillators Feature Summary

• DualMEMS temperature sensing and TurboCompensation technology provide resistance to airflow, thermal gradients, shock, and vibration.
• Integrated multiple on-chip regulators filter power supply noise, removing the requirement for dedicated external low-dropout regulators.
• Factory programmable for specific frequency, stability, voltage, output signaling, and pull range combinations.

Oscillators Applications

• Telecommunications systems requiring precise clocking
• Networking equipment demanding low-jitter differential signals
• Industrial applications operating in noisy environments

Oscillators Procurement Notes

Verify the complete part number string including all suffixes against official SiTime documentation to ensure correct output format, voltage, and stability specifications. Confirm that the HCSL output type matches the target receiver requirements. Check for any specific manufacturing notes regarding reflow profiles or tape and reel dimensions required for proper assembly integration.

Oscillators Selection Notes

Select this component when a differential MEMS VCXO with HCSL outputs is required for 61.44 MHz applications. Ensure the 3.3 V supply voltage aligns with the system design. Consider the ±35 ppm stability and wide operating temperature range for environmental robustness. Verify that the integrated noise filtering capabilities meet the power integrity requirements of the application.

Oscillators Part Context

This model belongs to the SiT3372 family of ultra-low jitter differential MEMS VCXOs from 1 MHz to 220 MHz. The Elite Platform provides exceptional phase noise and dynamic performance. The AC variant indicates specific commercial temperature and stability grades. The family supports LVPECL, LVDS, and HCSL outputs with various pull range options.

Oscillators Replacement Considerations

Direct substitutes include other SiT3372 variants with matching 61.44 MHz frequency and HCSL output, such as SIT3372AC-4E9-30NC61.440000 if LVPECL is acceptable. Cross-compatibility with quartz VCXOs requires verification of pinout, voltage levels, and pull range linearity differences.
