Oscillators Procurement Notes

Verify the specific output format against design requirements, as datasheets indicate LVDS availability for this series while distributor listings may vary. Confirm package dimensions and thermal characteristics match the PCB layout. Ensure supply voltage constraints align with system power rails before integration.

Oscillators Selection Notes

Select this component when a 74.25 MHz signal with ±25 ppm stability is required in a compact surface-mount form factor. Consider the -20°C to +70°C industrial temperature range for environmental suitability. Verify compatibility with LVPECL receiver inputs on the target circuit board.

Oscillators Part Context

This part belongs to the SiT9120 family of fixed-frequency differential oscillators. The series offers various package sizes including 3225, 5032, and 7050, supporting frequencies from 25 MHz to 212.5 MHz. It is designed for applications demanding low phase jitter and robust performance in consumer and industrial electronics.

Oscillators Replacement Considerations

Cross-reference with other SiT9120 variants such as SIT9120AC-2DF-25E74.250000 if LVDS output is preferred over LVPECL. Ensure substitute parts maintain the same 74.25 MHz frequency and ±25 ppm stability specifications.
