HDSL Transformers
inductance
± 6% (mH)
These HDSL transformers have been designed to work
with a variety of specific transceiver chips to provide
2B1Q coded data transmission.
They’re engineered for low leakage inductance and
return loss as well as high line isolation. Longitudinal
balance and THD are optimized for the best overall
performance at a given transmission speed.
Coilcraft can also custom engineer a transformer to
meet your specific requirements. For free evaluation
samples, contact Coilcraft or visit www.coilcraft.com.
