Oscillators Procurement Notes

Verify the exact part number against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the LVPECL output format and 204.8 MHz frequency align with the target circuit design requirements. Confirm that the 3.0 V supply voltage and 25 ppm stability meet system tolerances. Check for any specific ordering suffixes that may affect packaging or lead times directly with the supplier.

Oscillators Selection Notes

Select this component when differential LVPECL outputs are required for low-jitter applications. The MEMS-based architecture offers superior robustness against environmental stressors compared to traditional quartz. Consider the factory programmability for customizing pull range and stability without redesigning the oscillator core. Ensure the 3225 package size fits the PCB layout constraints and that the operating temperature range covers the intended environment.

Oscillators Part Context

The SiT3372 series comprises ultra-low jitter differential MEMS VCXOs designed for frequencies between 1 MHz and 220 MHz. This model represents a specific configuration within that family, optimized for 204.8 MHz operation with LVPECL outputs. The series leverages SiTime’s proprietary compensation technologies to deliver high performance in demanding environments while allowing for flexible customization through factory programming.

Oscillators Replacement Considerations

Direct substitutes must match the 204.8 MHz frequency, LVPECL output, and 3225 package dimensions. Verify that alternative MEMS VCXOs support similar pull ranges and stability metrics. Cross-reference pin configurations and supply voltage requirements to ensure electrical compatibility without circuit modification.
