| Document 216-1 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 optimum performance with a variety of GlobeSpan ADSL chipsets. They feature very low leakage inductance, stable primary inductance from -40C to +85C 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.
