Oscillators Procurement Notes

Verify the complete part number including suffixes against official SiTime documentation to ensure correct frequency, stability, and package specifications. Confirm that the LVPECL output type and 2.5V supply voltage match the design requirements. Check for RoHS compliance status and ensure the ordering quantity aligns with tape and reel packaging standards provided by the manufacturer.

Oscillators Selection Notes

Select this model when a 14.4 MHz VCXO with LVPECL outputs is required. Ensure the ±50 ppm stability and ±3145 ppm pull range meet system constraints. Verify that the 2.5V supply voltage and 3.2x2.5mm package dimensions fit the PCB layout. Consider the -20°C to +70°C operating range for environmental suitability.

Oscillators Part Context

This component belongs to the SiT3372 Elite Platform series, which offers ultra-low jitter differential VCXOs ranging from 1 MHz to 220 MHz. The platform supports various output types including LVPECL, LVDS, and HCSL. It is designed to eliminate long lead times associated with custom quartz devices by allowing factory programming of unique specifications.

Oscillators Replacement Considerations

Direct substitutes must match the 14.4 MHz frequency, LVPECL output, 2.5V supply, and 3.2x2.5mm package. Verify compatibility with ±50 ppm stability and ±3145 ppm pull range. Cross-reference pinouts and electrical characteristics to ensure functional equivalence in the target circuit.
