For Globespan  
ADSLTransformers chip sets  
This product is not RoHS-compliant. Contact Coilcraft  
for current status or possible alternatives.  
These transformers have been designed to provide opti-  
mum performance with a variety of GlobeSpan ADSL  
chipsets.  
They feature very low leakage inductance, stable pri-  
mary inductance from 40°C to +85°C and longitudinal  
balance optimized for the best overall performance at  
the ADSL transmission speed.  
For free evaluation samples or to discuss custom de-  
signs, contact Coilcraft or visit www.coilcraft.com.
