Channel-to-Channel Matching
Channel-to-channel matching is the absolute value of the difference
in propagation delays between the two channels when operated
with identical loads.
Minimum Pulse Width
The minimum pulse width is the shortest pulse width at which
the specified pulse width distortion is guaranteed.
Maximum Data Rate
The maximum data rate is the fastest data rate at which the
specified pulse width distortion is guaranteed.
