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.
