Oscillators Selection Notes

Select this model when a 614.4 MHz VCXO with HCSL outputs is required for low-jitter applications. Ensure the 2.8V supply voltage aligns with the target circuit design. Consider the ±50 ppm stability specification for frequency accuracy needs. Verify the operating temperature range meets environmental constraints.

Oscillators Part Context

The SiT3373 series represents SiTime's family of differential MEMS VCXOs designed for frequencies between 220 MHz and 725 MHz. These devices replace traditional quartz VCXOs, offering superior shock resistance and lower phase noise. The AI-4B3-28NZ variant specifically denotes the 2.8V operation and 614.4 MHz frequency setting within this lineup.

Oscillators Replacement Considerations

Direct substitutes may include other SiT3373 variants with different supply voltages or frequencies, such as those operating at 3.3V. Cross-compatibility with quartz VCXOs requires careful evaluation of jitter specifications and output drive levels. Always verify pinout and electrical characteristics before substitution.
