Application Notes
A typical ATM 25.6 application circuit is shown. The sug-
gested application circuit supports operation over shielded
twisted pair or unshielded twisted pair media. Note that both
channels are identical in the PE-67583.
The components and guidelines in this note should serve
as a starting point for design. The circuit and layout of an
ATM 25.6 interface requires that special attention be given
to the selection of components and their placement to
reduce induced noise. The optimum external circuit values

are dependent upon the individual layout, operating condi-
tions, and specific cabling requirements. Pulse transformers
are designed for use in ATM 25.6 Mbps applications that
require a low frequency cutoff below 12 KHz.
It is important not to connect both UTP and STP media
simultaneously. The module has been optimized to sup-
port only one media connection at a time.
