differential pair by matching the electrical length of the
traces.

Output Termination
Terminate outputs through 50Ω to V
CC
- 2V or use an
equivalent Thevenin termination. When a single-ended
signal is taken from a differential output, terminate both
outputs. For example, if Q0 is used as a single-ended
output, terminate both Q0 and
Q0.
