Procurement Notes

Verify the specific factory configuration code embedded in the ordering suffix against the datasheet's Ordering Information table. Confirm that the required output frequencies and signal formats match the pre-programmed NVM settings for this specific part number variant.

Selection Notes

Select this model when fixed, pre-configured clock signals are required without field programming. Ensure the internal configuration matches the target system's frequency and format needs. For custom frequencies, consider variants with blank configuration codes or use the SI5338-PROG-EVB kit for field programming.

Part Context

This component belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete crystal oscillators by generating any frequency on each of its four outputs. The 'C' designation typically indicates a specific factory configuration within the broader Si5338 product line.
