PC Board Layout
The design of the printed circuit board (PCB) should
follow good layout practices, such as keeping bypass
capacitors close to the supply pins, keeping output signals
away from input signals, the use of ground and power
planes, etc. In addition, the layout of the PCB can also
affect the isolation transient immunity (CMTI) of the ACPL-
C87x, primarily due to stray capacitive coupling between
the input and the output circuits. To obtain optimal CMTI
performance, the layout of the PC board should minimize
any stray coupling by maintaining the maximum possible
distance between the input and output sides of the circuit
and ensuring that any ground or power plane on the PC
board does not pass directly below or extend much wider
than the body of the ACPL-C87A. The placement of the
input capacitor which forms part of the anti-aliasing filter
together with the resistor network should also be placed
as close as possible to the Vin pin.
