Document 216-1
Revised 08/20/07
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.
