Akros Silicon is a fabless semiconductor company bringing managed power to the network edge. Akros provides fundamental innovation for seamless integration of Power over Ethernet (PoE) control, power management and interface to the Ethernet world.

Akros has developed break-through, innovative integrated circuit solutions using proprietary precision analog and mixed-signal technologies. Akros’ unique system-orientated designs and architecture allow the control of Electro Magnetic Interference (EMI) and provide immunity against surge transients, while managing power and Ethernet performance.

EMI and Surge performance is critical to shipping systems compliant with US and international standards. Akros designs address such standards right from the start. System designers can take advantage of Akros' technology to develop products that meet EMC compliance by design, minimizing the number of board turns and substantially improving time-to-market.

Key Products

AS1602

Dual Channel ACTIVE EMI & ESD Suppressor for Ethernet Applications

The AS1602 is a single-chip, highly integrated CMOS solution for EMI (Electro-Magnetic Interference) & ESD (Electro-Static Discharge) Suppression in Ethernet applications. Electro-Magnetic Compatibility (EMC) is one of the most challenging aspects of system design that very often results in product release delays. The AS1602 is designed to address EMC Compliance (both EMI and ESD) in the early phase of the system design and enables the “Design for EMC” concept.

 

 

The AS1602 can be used in any type of 10Base- T/100Base-TX/1000Base-T systems, in both Power-over- Ethernet (POE) and non-POE ports. Applications include; compliance to EMI Emissions (CISPR22 and FCC Part 15, Class B requirements for Radiated and Conducted \Emissions), EMI Immunity standards (IEC61000-4-3/6 requirements for Radiated and Conducted Immunity, Level 3 or higher), IEC61000-4-2 Air/Contact Discharge protection (±25kV Air, ±12kV Contact), as well as Cable Discharge Events protection (±12kV). The AS1602 utilizes Akros Silicon's patented “Active Choke Technology” that offers superior Common Mode (CM) noise reduction and CM immunity compared to passive filtering techniques in Ethernet applications. At the system level, the AS1602 provides additional CM noise suppression of more than 10dB over the entire Ethernet signal bandwidth. The AS1602 works with standard Ethernet Physical Layer Transceivers (PHY) and Ethernet transformers. System designers can use the AS1602 to design systems for EMC compliance while maintaining full Ethernet electrical compliance per the IEEE 802.3 specification.

AS1135

30W Powered Device (PD) with Integrated low-emission DC-DC Converter

The AS1135 is a single-chip, highly integrated CMOS solution for Power over Ethernet (PoE) Powered Devices requiring input power 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 AS1135 integrates input Surge Protection, a PD controller, and a low-emission DC-DC controller. The AS1135 implements all the physical layer Powered Device (PD) functionality as required by the IEEE® 802.3af-2005 and IEEE® 802.3at (Draft 3.0) standards. This includes 2-event classification, Type2 PSE detection indicator (ATDET) in addition to PD detection, under-voltage lockout, and hot-swap FET integration.

The AS1135 has been architected and designed to address both EMI emission concerns and surge/over-voltage protection in POE applications. The AS1135 implements many design features that minimizes transmission of system common-mode noise on to the UTP. On-chip integration of surge protection provides faster ressponse to surge events and limits stray surge current from passing through sensitive circuits, such as the Ethernet PHY device. The device is designed to provide a safe low impedance discharge paths directly back to the earth ground, resulting in superior reliability and circuit protection.

By using high-volume standard CMOS technology, Akros enables its customers to implement higher performance PoE devices with low cost and a small footprint.
