Other Parts Discussed in Thread: TIDA-00207
According to the ETHERNET standard, clause 8.3.2.1.
Isolation shall withstand at least one of the following electrical strength tests:
a) 1500 V rms at 50 Hz to 60 Hz for 60 s, applied as specified in 5.3.2 of IEC 60950: 1991.
b) 2250 Vdc for 60 s, applied as specified in 5.3.2 of IEC 60950: 1991.
If you refer to the standard for PCBs IPC-2221A, Table 6-1. There are recommendations on the gaps between the conductors on the printed circuit board. For convenience of calculation, I used the program Saturn PCB.
As you can see, the minimum clearance should be 3.85mm! However, on the printed circuit board in the reference design TIDA-00207, such a gap is not observed. Here is an example from an open pcb file:
How would you comment on this? This is my fault or yours?
Thanks in advance for the answer!
