ADSL Interface Transformers
For Virata
Beryllium chipset
These transformers provide coupling and line isolation
for ADSL interfaces using the Virata Beryllium chip set.
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
ADSL transmission speeds.
In addition to the standard model shown, Coilcraft can
provide custom transformers with other turns ratios.
For free evaluation samples or to discuss custom de-
signs, contact Coilcraft or visit www.coilcraft.com.
