parasitic board capacitance. This maintains the good
matching characteristics of the low-to-high and high-to-
low transitions of the LTC1685. Note that output “A” to
output “B” capacitance should also be minimized. If routed
adjacent to each other on the same layer, they should be
separated by an amount at least as wide as the trace
widths. If output “A” and output “B” are routed on different
signal planes, they should not be routed directly on top of

each other. A trace width’s lateral separation is also
recommended.
As mentioned before, care should also be taken when
routing the “DI” input. To achieve consistent board-to-
board propagation delay, the ringing on this signal should
be kept below a few hundred millivolts.
