SIT3372AC-4B3-28NC200.000000

Oscillators Overview

The SiTime SIT3372AC-4B3-28NC200.000000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 200 MHz. It utilizes DualMEMS temperature sensing and TurboCompensation technology for dynamic performance. The device features an HCSL output format and operates on a 2.8V supply voltage with a range of 2.52V to 3.08V. Frequency stability is specified at ±50 ppm, with an absolute pull range of ±145 ppm. It is housed in a compact 6-pin surface-mount package measuring 7 mm x 5 mm x 0.85 mm, designed for industrial applications requiring low jitter and resistance to environmental stressors.

Oscillators Feature Summary

• Integrates DualMEMS temperature sensing and TurboCompensation technology to provide exceptional resistance to airflow, thermal gradients, shock, and vibration.
• Includes multiple on-chip regulators that filter power supply noise, eliminating the requirement for dedicated external Low-Dropout (LDO) regulators.
• Factory programmable for specific combinations of frequency, stability, voltage, output signaling, and pull range to optimize clock configurations.

Oscillators Applications

• Telecommunications systems requiring precise timing
• Networking equipment demanding low-jitter differential clocks
• Industrial applications operating in noisy or thermally variable environments

Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct configuration parameters. Confirm that the HCSL output format and 200 MHz frequency match system requirements. Check RoHS compliance status and manufacturing notes for proper reflow profile specifications during assembly. Ensure the 6-pin SMD package dimensions align with PCB layout constraints.

Oscillators Selection Notes

Select this component when a differential VCXO with high immunity to mechanical and thermal stress is required. The integrated noise filtering simplifies power design by removing external LDOs. Factory programmability allows for customized pull ranges and frequencies without custom quartz lead times. Verify that the HCSL output interface is compatible with the downstream receiver logic levels.

Oscillators Part Context

This model belongs to the SiT3372 family of ultra-low jitter differential MEMS VCXOs from SiTime. The series covers a frequency range from 1 MHz to 220 MHz. The AC suffix typically denotes commercial temperature range operation. The family is engineered to replace traditional quartz oscillators in applications requiring robustness against vibration and thermal gradients while maintaining precise timing accuracy.
