| Document 394 -1 VDSL Transformers For Ikanos SmartLeap This product is not RoHS-compliant. Contact Coilcraft for current status or possible alternatives. These surface mount transformers are designed specifically for use with the Ikanos SmartLeap chipset series for high-speed telecom applications. They are available in 6-pin and 8-pin versions for both ANSI and ETSI standards. They all feature 60 dB minimum longitudinal balance, -75 dB maximum harmonic distortion and 1500 V winding-to-winding isolation. Coilcraft can also custom engineer transformers to meet your specific requirements. For free evaluation samples, contact Coilcraft or visit www.coilcraft.com.
