If you have a physical chip with this marking: input into complex supply lines necessary for TFT

Used for software resets, enabling auto-negotiation, selecting speed (10/100Mbps), and forcing full/half-duplex modes.

A 50 MHz clock injected straight into the REF_CLK pin when operating in RMII mode. Ensure this trace is short to avoid EMI propagation. Power Supply Decoupling ceramic capacitors immediately adjacent to every VDDcap V sub cap D cap D end-sub

Manufactured by Microchip Technology (acquired from Micrel), this chip is favored for its low power consumption, small footprint, and integrated termination resistors, which reduce the overall Bill of Materials (BOM) cost.

The host processor communicates with the KSZ8081 via the MDIO/MDC serial interface. This allows the host to read link status, speed, and duplex, or to write configuration changes.
