Programmable Oscillators Procurement Notes

Verify the specific output frequency and any required programming configurations before procurement, as this is a programmable device. Confirm that the LVDS output format aligns with the target circuit requirements. Ensure the 3.3 V supply voltage and 50 PPM stability meet the system specifications. Check for updated datasheets regarding I2C programming details.

Programmable Oscillators Selection Notes

Select this model when a programmable LVDS clock source is required within the 10 MHz to 810 MHz range. It is suitable for designs needing I2C configurability and moderate phase noise performance. Consider the 7x5 mm footprint for PCB layout constraints. Evaluate if the 50 PPM stability suffices compared to higher precision alternatives in the same series.

Programmable Oscillators Part Context

This component belongs to the Si591 family of standard oscillators manufactured by Skyworks Solutions. The series offers various output formats including CMOS, LVPECL, and LVDS. The 591NA variant specifically denotes the LVDS output option with I2C programmability, distinguishing it from fixed-frequency or different output type models in the lineup.

Programmable Oscillators Replacement Considerations

Direct substitutes include other Skyworks Si591 series parts with matching LVDS outputs and similar packages, such as the 591NB series. Verify that alternative part numbers support the required I2C programming interface and maintain compatible electrical characteristics.
