Procurement Notes

Verify the complete part number including suffixes such as 'E' or 'Q' against official Renesas documentation, as these often denote specific package types, temperature ranges, or lead-free compliance status. Confirm RoHS and REACH compliance details directly from the manufacturer's datasheet before procurement. Ensure compatibility with existing board layouts and power supply specifications defined in the electrical characteristics section of the official specification sheet.

Selection Notes

Select this component when designing systems requiring dedicated Gigabit Ethernet clocking solutions. Evaluate the specific frequency outputs needed for the target PHY chip. Consider the package type availability and thermal management requirements associated with the selected suffix. Verify that the device's operating voltage and current consumption align with the system's power budget and environmental constraints.
