Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the programmed configuration, as the base model supports various frequencies. Ensure compatibility with the required output voltage levels (1.5, 1.8, 2.5, or 3.3 V) and signal formats (LVPECL, LVDS, HCSL, etc.) for the target application design.

Application Specific Clock/Timing Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single IC. Verify that the required output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Confirm that the input reference source matches one of the supported types, such as differential clocks up to 710 MHz.

Application Specific Clock/Timing Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. The 'Q' suffix typically denotes automotive-grade qualification or specific reliability standards, while the alphanumeric code following it indicates a factory-programmed configuration. The '-GM' suffix specifies the 24-lead QFN package type.

Application Specific Clock/Timing Replacement Considerations

Direct replacements within the same family include other Si5338 variants with different programming codes or output configurations. When substituting, ensure the replacement part supports the required output frequencies and signal formats. Verify that the pinout remains compatible, as all Si5338 variants share the same 24-QFN footprint.
