Figure 4. The Simple Option for Cable Continuity Detection
Lay-Out
During the time we have been experimenting with the
copper interface, it has become apparent that one major
source of problems is the computer noise coupled into
the transmitted and received signals. Little serial induc-
tors were added to the serial lines that come from the
PDT or ENDEC (TX, TY), and go to the PDR or EDS
(RX, RY), to filter high frequency components that do
not belong to the FDDI signal.
The protoypes we have built for preliminary testing were
based on FASTcards (ENDEC and EDS). The whole in-
terface circuit, including data path, bias resistors and
Link Detect, was plugged into the ODL footprint. The
newer generation of FASTcards based on PDT/Rs will
use exactly the same interface. Detailed schematics of
an S-port and an M-port are shown in Figures 5 and 6
respectively.
Since FCC compliance is dependent on both the circuit
characteristics and the system lay-out and configura-
tion, test results will vary from implementation to imple-
mentation. However, the circuit includes noise sup-
pressing elements to minimize EMI.
