SIT3373AC-1E3-25NX224.000000

Oscillators Overview

The SiTime SIT3373AC-1E3-25NX224.000000 is a differential MEMS voltage-controlled oscillator (VCXO) operating at 224 MHz with LVPECL output signaling and a 2.5V supply voltage. It features ±50 ppm frequency stability across the -20°C to 70°C industrial temperature range. The device utilizes DualMEMS technology for enhanced dynamic performance against shock, vibration, and thermal gradients. It integrates on-chip regulators to filter power supply noise, eliminating the need for external LDOs. The component is housed in a compact 6-SMD, No Lead Exposed Pad package.

Oscillators Feature Summary

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

Oscillators Applications

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

Oscillators Procurement Notes

Verify that the ordering suffix matches the required specifications exactly. Confirm the package type is 6-SMD with no lead exposed pad. Ensure the output signaling is LVPECL and the supply voltage is 2.5V. Check the frequency stability requirement of ±50 ppm over the -20°C to 70°C range. Validate the operating frequency is 224 MHz before procurement.
