Application Specific Clock/Timing Procurement Notes

Verify the specific factory programming configuration associated with the B04154 suffix against the design requirements using Skyworks ClockBuilder Pro software. Confirm that the QFN-24 package thermal characteristics and moisture sensitivity levels align with the assembly process specifications.

Application Specific Clock/Timing Selection Notes

Select this component when multiple independent clock frequencies are required from a single source with high precision. Ensure the input reference signal matches the supported voltage levels and formats, such as differential clocks up to 710 MHz or single-ended CMOS up to 200 MHz. Validate that the required output swing voltages (1.5 V, 1.8 V, 2.5 V, or 3.3 V) are compatible with the load devices.

Application Specific Clock/Timing Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'P' suffix typically denotes a specific factory-programmed configuration variant within the series, distinct from user-programmable versions. The 'GMR' indicates tape and reel packaging for surface-mount assembly.

Application Specific Clock/Timing Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory programming codes. Verify that alternative part numbers support the exact frequency set and output configurations required by the application.
