NAME
T3 and T4 are optional. For more information, contact the Telecom Support Group at
telecom.support@dalsemi.com.
A list of alternate transformer part numbers and manufacturers is available at
telecom.support@dalsemi.com.
The layout from the transformers to the network interface is critical. Traces should be at least 25
mils wide and separated from other circuit lines by at least 150 mils. The area under this portion
of the circuit should not contain power planes.
Some T1 (never in E1) applications source or sink power from the network-side center taps of
the Rx/Tx transformers.
The ground trace connected to the S2/S3 pair and the S4/S5 pair should be at least 50 mils wide
to conduct the extra current from a longitudinal power-cross event.
