The AS1124 is a single-chip, highly integrated CMOS solution for Power over Ethernet (PoE).
Applications include Voice over IP (VoIP) Phones, Wireless LAN Access Point, Security and Web Cameras, Analog Telephone Adapters (ATA) and Point of Sales Terminals.
Key Features
that minimizes transmission of system common-mode noise on to the UTP while providing high immunity to over-voltage and surge events. By using high-volume standard CMOS technology, Akros enables its customers to implement higher performance PoE devices with low cost and a small footprint.

gle-chip, highly integrated CMOS solution for Power over Ethernet (PoE). Applications include Voice over IP (VoIP) Phones, Wireless LAN Access Point, Security and Web Cameras, Analog Telephone Adapters (ATA) and Point of Sales Terminals. The AS1124 provides the functions required for power over Ethernet Powered Device (PD) applications. The AS1124 integrates rectification and protection circuitry, a PD controller, and a DC-DC converter. This high level of integration provides faster ressponse to surge events and limits stray surge current from passing through sensitive circuits, such as the Ethernet PHY device.
