Pattern Generator Specifications and Characteristics
(16821A, 16822A, and 16823A)
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).
