MC33771C TPL Termination at second port

[avinash1588]

Hey,

I am using two MC33771C in Daisy Chain with S32K144 on the single PCB board. I am using MC33664 for Isolated communication between first MC33771C and MCU & using Capacitor isolation for communicating between two MC33771C devices. I don't want to connect third IC to Daisy chain, so I want to Terminate second / output port of second MC33771C IC in daisy chain.

So please let me know how to terminate the second / output port of MC33771C or should I just leave pins RDTX_OUT+ and RDTX_OUT- floating as shown in RD33771-48EVM reference design as shown below ?

Hey NXP Team, 

One more question, I have designed my Schematic and I want to get it Reviewed from your team, so please let me know what should I do for that ?

And it is confidential so I can't share it in public.

Yes, you can leave pins RDTX_OUT+ and RDTX_OUT- floating.
