Figure82 Output Routes (Differential)
A single-ended signal or a pair of differential signals can be
output from multiple pogo pins at the same time. However,
there are restrictions for the combination of the pogo pins.
Because each pair of adjacent pogo pins, A+ and B+, A- and
B-, C+ and D+, and C- and D- shares the same output ampli-
fier, these pairs cannot be used at the same time. The fol-
lowing table summarizes the restrictions.

Mode Possible Pogo Pin Combinations
Single-ended All or some of following combinations:
A+ or B+, A- or B-, C+ or D+, C- or D-
Differential All or some of following combinations:
Pair of A+/A- or B+/B-, Pair of C+/C- or D+/D-
Mix of single-ended and
differential
Following two cases:
(a) Single-ended A+ or B+, and/or A- or B-,
AND differential pair of C+/C- or D+/D-
(b) Single-ended C+ or D+, and/or C- or D-,
AND differential pair of A+/A- or B+/B-
