Part Number: ISO7842
There is a schematic example in Figure 21. There is numbers 10 mils, 40 mils and 10 mils in vertical direction.
The numbers are for maintaining the impedance for high speed data, not for isolation barrier. The distance can be changed if we can control the impedance. Is my understanding correct?
There is a slit under IC in figure 21. Is this slit needed? If yes, is it for maintain the creepage distance?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
