Quad Channel Active EMI & ESD Suppressor for Ethernet Applications Features Brief Description Enables system designers to comply with: The KTA1552 is a four channel, highly integrated CMOS solution for Common Mode (CM) noise suppression & CISPR22 and FCC Part 15, Class B transient voltage protection in Ethernet applications. requirements for Radiated and Conducted Emissions The KTA1552 EMI/ESD Suppressor has been architected IEC 61000-4-3 requirements for Radiated and and designed to provide system level ESD protection and Conducted Immunity, Level 3 or higher EMI suppression in Ethernet products, enabling an easier IEC 61000-4-2 ESD (Air Discharge) of 25kV path to system EMC compliance. IEC 61000-4-2 ESD (Contact Discharge) of The KTA1552 utilizes Kinetic Technologies patented 12kV Active Choke technology which offers superior Common Cable Discharge Event (CDE) of 12kV Mode reduction and immunity compared to passive filtering Provides up to 10dB of additional common techniques in Ethernet applications. The adaptive and mode noise suppression over the frequency of continuous suppression operates over the entire Ethernet 1MHz to 125MHz when used with Ethernet signal bandwidth, and it compensates for many variables magnetics that are the source of common mode noise in Ethernet Robust built-in ESD suppressors protect the systems. It also improves the differential-to-common mode Ethernet PHY and improve system ESD balance of the system. This enables system designers to performance meet EMI emissions and EMI immunity requirements from JESD22-A114, ESD, HBM of 8kV the start of the design. Interfaces to standard Ethernet transformers In addition, the KTA1552 includes highly robust ESD/Surge and 1000 Ethernet PHYs protection diodes to protect the Ethernet PHY from various Uses a single standard power rail (3.3V or 2.5V) transient overvoltage events. These are built using Open drain output stage that can be biased Kinetics proprietary design and layout techniques to safely from 1.8V to 3.3V using transformer center-tap deal with very high current densities in a CMOS process supply as needed based on choice of Ethernet without creating voltage and/or thermal overstress that PHY. causes damage to the device. Flow-through routing for ease of board layout The KTA1552 supports four twisted pair interfaces for 1000 Typical power consumption of 90mW. applications.
