August 17, 2012 Rev. 1.0 4/23 KSZ9031MNX-EVAL Board User's Guide 1.0 Introduction 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. 2.0 * * * * * * * * * 3.0 Board Features Micrel KSZ9031MNX 10Base-T/100Base-TX/1000Base-T Physical Layer Transceiver RJ-45 Jack for Ethernet cable interface Auto MDI/MDI-X for automatic detection and correction for straight-through and crossover cables GMII Loopback for standalone 1000Mbps evaluation MII Connector to interface with 10/100Mbps MAC controller/switch LED Indicators for link status and activity Jumpers to configure strapping pins Manual Reset Button for quick reboot after re-configuration of strapping pins USB port for MDC/MDIO programming access to KSZ9031MNX PHY registers Evaluation Kit Contents The KSZ9031MNX Evaluation Kit includes the following hardware: * KSZ9031MNX-EVAL Board (a.k.a.

August 17, 2012 Rev. 1.0 6/23 KSZ9031MNX-EVAL Board User's Guide 4.1 Jumper Setting & Definition At power-up, the KSZ9031MNX device is configured via strapping pins that are set by external pull-up and pull-down resistors. The KSZ9031MNX-EVAL board provides jumpers for the KSZ9031MNX device strap-in settings and for selective board options. Jumpers allow for quick configuration and re-configuration. To override the current KSZ9031MNX device and board settings, simply select and close the desired jumper setting(s) and toggle the on-board manual reset button (S1) for the new setting(s) to take effect. The KSZ9031MNX-EVAL board jumper settings are defined in the table below.
