HDSL2Transformers  
This product is not RoHS-compliant. Contact Coilcraft  
for current status or possible alternatives.  
This family of transformers provides optimum perfor-  
mance with the Level One SK70740/-41/-42 and other  
HDSL2 transceiver chip sets. The series now includes  
parts with a 1 CT to 2.3 CTS turns ratio, allowing them to  
work with line drivers for lower power supply voltages.  
They’re engineered for minimum DC resistance and  
very low leakage inductance. Primary inductance with  
and without DC bias is stable from -40°C to +85°C.  
The return loss, longitudinal balance and THD are  
optimized for the best overall performance at the  
HDSL2 transmission speed.  
For free evaluation samples or to discuss custom de-  
signs, please contact Coilcraft.
