Document 202-1 HDSL2 Transformers This product is not RoHS-compliant. Contact Coilcraft for current status or possible alternatives. This family of transformers provides optimum performance 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 designs, please contact Coilcraft.
