NAME
DESCRIPTION
F1 and F2
1.25A slow blow fuse
S1 and S2
25V (max) transient suppressor
S3 andS4
77V (max) transient suppressor
Transformer 1:1CT and 1:136CT (5.0V, SMT) (Note 1)
T1 and T2
Transformer 1:1CT and 1:2CT (3.3V, SMT) (Note 1)
T3 and T4
Dual common-mode choke (SMT)
Note 1:
T3 and T4 are optional. For more information, contact the Telecom Support Group at
Note 2:
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.
Note 3:
Some T1 (never in E1) applications source or sink power from the network-side center taps of the Rx/Tx
transformers.
Note 4:
