Data Cable Characteristics Without a Data Pod
The Agilent 16720A and 16522A data cables without a data pod provide an ECL terminated (1 K
Ω
to
–5.2V) differential signal (from a type 10E156 or 10E154 driver). These are usable when received by
a differential receiver, preferably with a 100
Ω
termination across the lines. These signals should
not be used single ended due to the slow fall time and shifted voltage threshold (they are not ECL
compatible).
