The AS1138 is a single-chip, highly integrated CMOS solutionfor Power over Ethernet (PoE) Powered Devices requiring inputpower of up to 30Watts. 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.The AS1138 integrates input surge protection, a PD controllerand a low-emission DC-DC controller. The AS1138 implementsall of the physical layer Powered Device (PD) functionality, asrequired by IEEE® 802.3af-2005 and IEEE® 802.3at-2009standards. This includes 2-event classification, Type 2 PSEdetection indicator (ATDET), PD detection, under-voltage lockout (UVLO), and Hot-Swap FET integration.The AS1138 has been architected to address both EM emissionconcerns and surge/over-voltage protection in PoE applications.The chip implements many design features that minimizetransmission of system common-mode noise onto theUnshielded Twisted Pair (UTP). On-chip integration of surgeprotection provides faster response to surge events and limitsstray surge current from passing through sensitive circuits, suchas the Ethernet PHY. The device is designed to provide safe,low-impedance discharge paths directly to the earth ground,resulting in superior reliability and circuit protection.By using high-volume standard CMOS technology, Akrosenables its customers to implement higher-performance PoE devices with low cost and a small footprint.TYPICAL APPLICATIONS Pan, tilt and zoom (PTZ), security and web cameras Voice over IP (VoIP) phones Wireless LAN access points, WiMax terminals Point-of-sale (PoS) terminals, RFID terminals Thin clients and notebook computers Fiber-to-the-home (FTTH) terminal
