SNLA338A January 2020 – August 2022 DP83826E
While the KSZ8081MNX/RNB and the DP83826 have many similarities, several extra features are included in the DP83826, improving performance and system optimization. This system rollover document outlines how to replace the Microchip KSZ8081MNX/RNB PHY with TI’s DP83826 by comparing differences including required external components, pin functions, feature set, and register operation. The impact to a design is dependent on the PHY configuration and features used.
