Introduction
The Holt HI-5200 is a 10Base-T/100Base-TX physical layer transceiver with both MII and RMII MAC
interfaces. It utilizes a unique mixed-signal design to extend signaling distance while reducing power
consumption, and offers HP Auto MDI/MDI-X for reliable detection of and correction for crossover and
straight-through cables. The device comes in a 32-pin, lead-free QFN package and provides an ideal
solution for 10Base-T/100Base-TX applications that have limited PCB board space.
The HI-5200 ADK evaluation board, ADK-5200, provides a convenient platform to evaluate HI-5200
features. All device configuration pins are accessible either by jumpers, test points or interface
connectors on the board.
