AS1602 is a single-chip, highly-integrated CMOS solution for EMI and ESD suppression in Ethernet applications

Image of Akros Silicon's AS1602, Dual-Channel ACTIVE EMI and ESD Suppressor for Ethernet ApplicationsThe AS1602 by Akron Silicon is a single-chip, highly-integrated CMOS solution for EMI (Electro-Magnetic Interference) and 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 (±25 kV Air, ±12 kV Contact), as well as Cable Discharge Events protection (±12 kV). 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 10 dB 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.
