1-Port Gigabit Ethernet PHY - Evaluation Board

The KSZ9031MNX is a completely integrated triple speed (10Base-T/100Base-TX/1000Base-T) Ethernet Physical Layer Transceiver for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable.

The KSZ9031MNX reduces board cost and simplifies board layout by using on-chip termination resistors for the four differential pairs and by integrating a LDO controller to drive a low cost MOSFET to supply the 1.2V core. On the copper media interface, the KSZ9031MNX can automatically detect and correct for differential pair misplacements and polarity reversals, and correct propagation delays and re-sync timing between the four differential pairs, as specified in the IEEE 802.3 standard for 1000Base-T operation. The KSZ9031MNX provides the industry standard GMII/MII (Gigabit Media Independent Interface / Media Independent Interface) for connection to GMII/MII MACs in Gigabit Ethernet Processors and Switches for data transfer at 1000 Mbps or 10/100Mbps speed. The KSZ9031MNX Evaluation Board (KSZ9031MNX-EVAL) provides a comprehensive platform to evaluate the KSZ9031MNX features. All KSZ9031MNX configuration pins are accessible either by jumpers, test points or interface connectors.
