QoS classification places frames into one of 8 priority queues per port. EEE reduces power during idle periods.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1-40<\/td><td>PHY Ports<\/td><td>5 GbE PHY differential pairs<\/td><\/tr><tr><td>41-60<\/td><td>MAC Interfaces<\/td><td>SGMII\/RGMII\/MII signals<\/td><\/tr><tr><td>61-80<\/td><td>Management<\/td><td>SMI\/MDIO, LED, strap pins<\/td><\/tr><tr><td>81-128<\/td><td>Power\/Control\/GND<\/td><td>VDD, GND, Reset, GPIO<\/td><\/tr><\/table>","application_scenarios":"<ul><li>SOHO Gigabit routers and switches<\/li><li>Wireless access points<\/li><li>Home gateways<\/li><li>IPTV set-top boxes<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>BCM53124<\/td><td>Broadcom<\/td><td>5-port GbE switch<\/td><td>QFN-128<\/td><\/tr><tr><td>KSZ9897<\/td><td>Microchip<\/td><td>7-port GbE switch<\/td><td>QFN-128<\/td><\/tr><tr><td>AR8327N<\/td><td>Qualcomm<\/td><td>7-port GbE switch<\/td><td>QFN-128<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9848","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=9848"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9848\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=9848"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=9848"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=9848"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=9848"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
