Applications include Voice over IP (VoIP) Phones, Wireless LAN Access Point, Security Cameras, WiMAX Terminals, Point-of-Sales Terminals, RFID Readers, Thin Clients and Notebook computers.<\/p>\n<p>The KTA1140 implements all of the physical layer Powered Device (PD) functionality, as required by IEEE\u00ae 802.3af-2003, IEEE\u00ae 802.3at-2009 and IEEE\u00ae 802.3bt- 2018 standards. This includes 5-event classification, Type 1-2 or 3-4 PSE detection indicators (PST1\/2 and PSDBT), PD detection, under-voltage lockout (UVLO), and Hot-Swap FET integration.<\/p>\n<p>The KTA1140 has been architected to address EM emission concerns in PoE applications. The chip implements many design features that minimize transmission of system common-mode noise onto the Unshielded Twisted Pair (UTP).<\/p>\n<p>The device is designed to provide safe, low-impedance discharge paths directly to the earth ground, resulting in superior reliability and circuit protection.<\/p>\n\t    <a
