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 spe-

cifically 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 distor-

tion 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
