Oscillators Procurement Notes

Verify the exact part number against official SiTime documentation to ensure correct configuration. Confirm that the ordering suffix matches the required output type, voltage, and pull range specifications for your design. Cross-reference the datasheet for reflow profile and tape and reel dimensions during manufacturing preparation.

Oscillators Selection Notes

Select this component when low jitter and high dynamic stability are critical. The integrated voltage control allows for frequency adjustment within the specified pull range. Ensure the application environment does not exceed the operational temperature limits defined in the datasheet. Consider the LVPECL output compatibility with downstream logic circuits.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series, designed for ultra-low jitter differential VCXO applications. The series supports frequencies from 1 MHz to 220 MHz. It replaces traditional quartz oscillators by offering programmability and robustness against environmental stressors like shock and vibration.

Oscillators Replacement Considerations

Direct replacements must match the 35.437431 MHz frequency, LVPECL output, and 3.3V supply. Verify pinout compatibility and thermal characteristics. Consult SiTime's parametric search for equivalent configurations if specific pull ranges or stabilities differ.
