QI have to drive a long cable (about 2m) with the ADuM2401 output signals,
synchronuos transmission and low speed (1Kb/s); any driving problems (cable
capacitance, current, ringing,...) ? Any suggestions ?
AThe maximum recommended output capacitance is 15 pF (a typical 2m cable might
have a capacitance of 200 pF). The part can actually source a decent DC load,
so higher capacitance at very low data rates might be OK. However the output
edge rates are relatively fast (2-3 ns) so there would likely be reflections.
You may want to consider an interface device specifically designed to drive
