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.

1. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc.
2. Leakage inductance tested across the primary with the secondary shorted.
3. Capacitance tested between windings with 0.1 Vrms applied at 80 KHz.
4. Stray capacitance tested across the primary with 0.1 Vrms applied at 2.5 MHz.
5. Operating temperature range −40°C to +85°C.
6. Electrical specifications at 25°C
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
