I have the following schematic using ADN4651 LVDS isolator:
The circuit works when all the TVS diodes are disconnected. When the TVS diodes are assembled the circuit does not work so I started removing the diodes one by one until it seems like the problem is with D2 and D4.
Thus, the circuit works with the TVS diodes but only if D2 and D4 are unassembled.
What could be the problem?
