Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix B04071 against the manufacturer's current datasheet to confirm factory-programmed NVM settings. Confirm package type is 24-QFN (4x4 mm). Check for moisture sensitivity classification and recommended reflow soldering profiles prior to assembly.

Application Specific Clock/Timing Selection Notes

Select this component when replacing multiple crystal oscillators with a single programmable source. Ensure input reference frequency matches available sources: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), or differential (5-710 MHz). Verify output voltage requirements match available VDDO options (1.5, 1.8, 2.5, or 3.3 V).

Application Specific Clock/Timing Part Context

This part belongs to the Si5338 family of quad clock generators. The 'Q' suffix typically denotes automotive grade qualification, while 'B' indicates a specific revision or feature set.
