Innovelec | KTA1552

Enables system designers to comply with:
- CISPR22 and FCC Part 15, Class B requirements for Radiated and Conducted Emissions
- IEC 61000-4-3 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
Industrial temperature range (-40°C to +85°C)
Dual Channel version available here
