Kinetic Technologies KTA1550 and KTA1552 Active EMI and ESD Suppressors are single-chip, highly integrated CMOS solutions for Common Mode (CM) noise suppression and transient voltage protection in Ethernet applications. The KTA1550 and KTA1552 deliver system level Electrostatic Discharge (ESD) protection and Electromagnetic Interference (EMI) suppression in Ethernet products, enabling an easier path to system Electromagnetic Compatibility (EMC) Compliance.
