Data cable characteristics without a data pod
The pattern generator data cables without a data pod provide an ECL terminated
(1 KΩ to –5.2 V) 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).
