Procurement Notes

Verify the exact part number suffix against official Infineon documentation, as variations may exist. Confirm current availability status, as this component may be subject to discontinuation or limited supply constraints. Ensure the ordering code matches the specific package and temperature grade required for the design. Cross-reference with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when designing systems requiring dedicated control for 10/100 Base-T/PHY switches. Ensure the host system provides a compatible parallel interface and operates within the 2.8V to 3.465V supply range. Verify that the thermal environment remains within the 0°C to 115°C operational limits. Consider the 128-BFQFP footprint during PCB layout planning to ensure adequate clearance and soldering requirements are met.
