AS1602 EMI/ESD Suppression IC

EMI/ESD Suppression IC

• Enables system designers to comply with:
• CISPR22 and FCC Part 15, Class B requirements for Radiated and Conducted Emissions.
• IEC 61000-4-3/6 requirements for Radiated and Conducted Immunity, Level 3 or higher.
• IEC 61000-4-2 ESD (Air Discharge) of ±25kV.
• IEC 61000-4-2 ESD (Contact Discharge) of ±12kV.
• Cable Discharge Event (CDE) of ±12kV.

• Provides up to 10dB of additional common mode noise suppression over the frequency of 1MHz to 125MHz when used with Ethernet magnetics.
• Robust built-in ESD suppressors protect the Ethernet Phy and improve system ESD performance.
• JESD22-A114, ESD, HBM of ±8kV.
• Interfaces to standard Ethernet transformers and 10/100/
• 1000 Ethernet PHYs.
• Uses a single standard power rail (3.3V or 2.5V).
• Open drain output stage that can be biased from 1.8V to 3.3V using transformer center-tap supply as needed based on choice of Ethernet Phy.
• Flow-through routing for ease of board layout.
• Typical power consumption of 90mW.
• Low power mode available for tight power budgets.
• Industrial temperature range (-40°C to 85°C).

Key Applications

• Ethernet systems requiring additional CM suppression to meet EMC Class B emissions or higher EMI immunity requirements and ESD protection.
• POE and Non-POE Ethernet systems
• VoIP Phones, IP Cameras, WAPs, Routers, Switches
• Set Top Boxes, Networked Printers and Appliances,
• Desktop and Laptop Computers
