Each of the 4 differential pairs has a center-tapped transformer winding for common-mode rejection. The 350\u00b5H OCL ensures adequate low-frequency response for 1000Base-T PAM-5 signaling. The center taps support PoE (Power over Ethernet) current injection or extraction.","pin_description":"<table><tr><th>Pin Group<\/th><th>Function<\/th><\/tr><tr><td>TX pair<\/td><td>Transmit center-tapped transformer<\/td><\/tr><tr><td>RX pair<\/td><td>Receive center-tapped transformer<\/td><\/tr><tr><td>BI_DA\/BI_DB<\/td><td>Bi-directional pairs A and B<\/td><\/tr><tr><td>BI_DC\/BI_DD<\/td><td>Bi-directional pairs C and D<\/td><\/tr><tr><td>Center taps<\/td><td>PoE \/ Bias voltage connections<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Gigabit Ethernet PHY coupling<\/li><li>Embedded Ethernet interfaces<\/li><li>Network switch transformers<\/li><li>Industrial Ethernet equipment<\/li><\/ul>","alternative_models":"<table><tr><th>Part Number<\/th><th>Manufacturer<\/th><th>Notes<\/th><\/tr><tr><td>H2019FNL<\/td><td>Pulse<\/td><td>Non-tape-reel version<\/td><\/tr><tr><td>749020023A<\/td><td>Wurth<\/td><td>Gigabit transformer alternative<\/td><\/tr><tr><td>ALT3232M-151-T001<\/td><td>TDK<\/td><td>Gigabit transformer<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/11066","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/comments?post=11066"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/11066\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media?parent=11066"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/categories?post=11066"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/tags?post=11066"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/chip_brand?post=11066"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
