On the transmit side, parallel data from the MAC (via MII or RMII) is encoded using 4B\/5B coding for 100BASE-TX or Manchester encoding for 10BASE-T, then scrambled and converted to MLT-3 signaling for output over twisted-pair cable. On the receive side, the incoming analog signal is equalized, decoded, and converted back to parallel data for the MAC. HP Auto MDI\/MDI-X automatically detects and corrects crossover cable wiring. The MIIM interface allows the host to configure PHY registers.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1-16<\/td><td>MII\/RMII<\/td><td>MAC interface signals (TXD, RXD, TXEN, RXDV, etc.)<\/td><\/tr><tr><td>17-20<\/td><td>MDIO\/MDC<\/td><td>Management interface<\/td><\/tr><tr><td>21-24<\/td><td>TX+\/-, RX+\/-<\/td><td>Ethernet differential pairs<\/td><\/tr><tr><td>25-28<\/td><td>VDD\/GND<\/td><td>3.3V supply and ground<\/td><\/tr><tr><td>29-32<\/td><td>LED\/INT\/CFG<\/td><td>LED outputs, interrupt, configuration straps<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Industrial Ethernet nodes<\/li><li>Embedded networking equipment<\/li><li>IoT gateways<\/li><li>Print servers<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>DP83848K<\/td><td>TI<\/td><td>10\/100 PHY MII<\/td><td>LQFP-48<\/td><\/tr><tr><td>LAN8720A<\/td><td>Microchip<\/td><td>10\/100 PHY RMII<\/td><td>QFN-24<\/td><\/tr><tr><td>KSZ8081MNX<\/td><td>Microchip<\/td><td>10\/100 PHY RMII<\/td><td>QFN-32<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9818","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=9818"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9818\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=9818"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=9818"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=9818"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=9818"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
