ADSL
Transformers
For Globespan
chip sets
This product is not RoHS-compliant. Contact Coilcraft
for current status or possible alternatives.
These transformers have been designed to provide op-
timum performance with a variety of GlobeSpan ADSL
chipsets.
They feature very low leakage inductance, stable primary
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 designs,
contact Coilcraft or visit www.coilcraft.com.
