Oscillators Procurement Notes

Verify the exact part number against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the selected variant matches the required output format and supply voltage constraints for your specific circuit design. Cross-reference the package dimensions to confirm PCB footprint alignment before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a differential HCSL output is required alongside VCXO tuning capabilities. Consider the ±35 ppm stability and 10 MHz pull range against system jitter budgets. Evaluate the 7050 package size for space-constrained layouts. Confirm that the -20°C to +70°C industrial temperature range meets the operational environment requirements.

Oscillators Part Context

This model belongs to the SiT3372 family of ultra-low jitter differential MEMS VCXOs. The series covers frequencies from 1 MHz to 220 MHz and offers various output formats including LVPECL and HCSL. The AC suffix indicates an industrial temperature grade, while the specific coding defines the voltage, stability, and packaging details unique to this configuration.

Oscillators Replacement Considerations

Direct substitutes must match the 125 MHz frequency, HCSL output, 7050 package, and ±35 ppm stability. Verify equivalent pull range and supply voltage compatibility. Consult official cross-reference lists for confirmed interchangeable part numbers.
