CC1125 RX in transparent mode: duty cycle issue

Didn't you conclude on this in the mail you sent me 28.11.2013?

TER, yes it's a part of it.

But in the past I thought it's only a TX issue. Now we figured out that RX also 'ruins' duty cycle and that's make us nervous again (had some new customer feedbacks we couldn't explain).

In this thread: http://e2e.ti.com/support/wireless_connectivity/f/155/t/265661.aspx you also looked at Rx performance. Since you have a small Rx bandwidth the resolution in Rx given by 1/(RX BW * 8) will be limited. 

Why does the duty cycle cause an issue? I would assume the impact of the duty cycle will depend on how the software is implemented.

In our own software we manage that. But there are customers who use our moduls since years and they detect e.g. baud rates depending on 'how long is the LOW-phase' of  a signal. With our old moduls, there has been no 'signal forming', they just passed through signal's duty cylce.

In my former thread I pointed to TX issues, I know.
But now it's regarding RX and again, why does the 112x deform the signals and is there any option to recover?

As I said the duty cycle will be dependent on the RX BW. Is it this limitation you are seeing?
