preliminary publication # 22355 rev: a amendment/0 issue date: april 1999 NETPHY-1lp-kt/m am79c874 evaluation kit using mii distinctive characteristics n based on the NETPHY?-1lp single port, low power, 10/100 mbps ethernet phy n provides complete mii connector to rj-45 connector functionality n provides jumpers to control test modes, phy address, mii or 7-wire (gpsi) mode n board connects directly into mii test equipment n led indicates the following: link, rx activity (in the rj-45 connector) duplex, speed/tx activity (on the board) n single 1:1 ratio magnetics module n power supplied via mii connector general description the NETPHY-1lp-kt/m evaluation kit has been devel- oped as a tool for evaluating the performance of the NETPHY-1lp device. the kit also serves as a design reference tool. the evaluation board has followed de- sign layout practices for optimum emi performance. the kit schematics and layout information provide ex- cellent guidance for integration of the NETPHY-1lp de- vice into individual designs. the evaluation board is con?gured for mii to rj-45 10base-t/100base-tx twisted pair cable operation. it does not support ?ber optic operation. a jumper al- lows use of the 7-wire general purpose serial interface (gpsi) via the mii connector for 10base-t operation. the evaluation board obtains 5-v power from the mii connector. the 5-v power is converted to 3.3-v by an on-board voltage regulator. the regulator can be by- passed to allow external 3.3-v voltage tolerance test- ing. five jumpers allow selection of one of 32 different phy addresses. the reset button is included as a convenient method of providing the hardware reset function. the NETPHY-1lp device provides excellent led ?exi- bility. the evaluation board has been designed to dem- onstrate one set of capabilities. the two leds on the rj-45 connector can provide steady or blinking feed- back to the user. the two leds directly on the evalua- tion board can provide steady, blinking, or bi-color feedback to the user. this ?exibility gives the designer multiple options for custom led look and feel front panels. evaluation kit contents n one 7 cm x 11 cm (2.5 in. x 4 in.)
