SIT3372AC-2B9-25NB148.351648

Oscillators Overview

The SiTime SIT3372AC-2B9-25NB148.351648 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 148.351648 MHz. It features LVDS output signaling and operates within a supply voltage range of 2.25 V to 2.75 V, typically powered at 2.5 V. The device exhibits a frequency stability of 25 ppm across the commercial temperature range of -20°C to +70°C. Housed in a compact 3.2 mm x 2.5 mm surface-mount package with a height of 0.85 mm, it utilizes DualMEMS temperature sensing and TurboCompensation technology for low-jitter performance.

Oscillators Feature Summary

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

Oscillators Applications

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

Oscillators Procurement Notes

Verify the exact part number SIT3372AC-2B9-25NB148.351648 against official SiTime documentation to ensure correct configuration parameters including frequency, stability, and output format. Confirm RoHS compliance and manufacturing lot traceability requirements prior to ordering. Check availability status as distribution channels may vary by region. Ensure proper handling procedures for MEMS devices during storage and assembly.

Oscillators Selection Notes

Select this component when a differential VCXO with 148.351648 MHz frequency and 25 ppm stability is required. Choose based on the need for LVDS outputs and operation within the -20°C to +70°C temperature range. Consider the integrated power regulation benefits for simplified board design. Evaluate the 3.2mm x 2.5mm package size constraints against available PCB real estate.

Oscillators Part Context

This model belongs to the SiT3372 family of ultra-low jitter differential MEMS VCXOs from SiTime. The family supports frequencies from 1 MHz to 220 MHz and offers programmability for various electrical specifications. The SiT3372 series is designed to replace quartz-based oscillators, offering superior resilience to environmental stressors and reduced customization lead times through factory programming capabilities.

Oscillators Replacement Considerations

Direct replacement requires matching the 148.351648 MHz frequency, LVDS output type, and 25 ppm stability specification. Verify that alternative MEMS VCXOs support the same 2.5V supply voltage and operate within the -20°C to +70°C range. Ensure the substitute component fits the 3.2mm x 2.5mm footprint and maintains comparable jitter performance for signal integrity compatibility.
