My customer is not able to communicate to SN65DSi83:
They forgot to have a cap connected to EN pin and they are not shure if EN=low during VCC startup.
Do you see as an issue preventing i2c communication after startup?
REFCLK is floating currently
would it be possible to connect it directly to GND?
Do you see this affecting the i2c communication?
I can share schematics internally if needed.
Thanks in advance for your help
