Hi.
I have testing the ISO7241C EVM on our test B/D
i found strange phenomenon that input signal voltage drop.,
When i have connected CLK signal(3.3V) with A, B, C port, CLK signal voltage drop 1.2V (VCC1 3.3V, VCC2 3.3V)
When i have not connected CLK signal with A, B, C port, CLK signal voltage is 3.3V
i want to know why input signal voltage drop.
I wish quick your response!!!
