KSZ8721BI

One of the standout features of the KSZ8721 is its integrated 10BaseT output filtering, eliminating the need for external filters and simplifying the design process. This transceiver is equipped with the necessary functions, including the Physical Medium Attachment (PMA), Physical Medium Dependent (PMD), and Physical Coding Sub-layer (PCS), to support both 100BaseTX and 10BaseT connections using a single set of line magnetics
