Failure mode of ADM2682 transceiver

Hello I'm RAMS engineer and in one of our design we foresee to use an ADM2682 transceiver.

Question we have is : is there a possibility for the Tx path to fail in a mode it randomly and continuously emits data ?

The internal design of these iCoupler is not well described, so we can't know if the encoder or decoder stages can have a failure mode were they erroneously encode and / or decode random bits (due to a unlocked PLL, a toggling buffer, jitter on a clock ...)

Can you provide me more information on this topic ?
