Codirectional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the isolation
barrier.
2
The
MSS
signal is glitch filtered in both speed grades, whereas the other fast signals are not glitch filtered in the B grade. To guarantee that
MSS
reaches the output
ahead of another fast signal, set up
MSS
prior to the competing signal by different times depending on speed grade.
3
SSAx = SSA0 or SSA1.
4
An internal asynchronous clock, not available to users, samples the low speed signals. If edge sequence in codirectional channels is critical to the end application, the
leading pulse must be at least 1 t
SSAx SKEW
ahead of a later pulse to guarantee the correct order or simultaneous arrival at the output.
