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.
