Hello Dave
The workaround seems to be a good solution but i wish to know if there is a better one.
Signal is braking constantly and periodicaly. I am switching it on and off for a longer and longer period. Ican send us the source code if necessary but the point of it is the following:
The interruptions can randomly last from a couple of nanosecond till 10 millisecs. This is simulating the insecure connection of an oxidized connector.
If we are talking about an ordinary user the interval of pulling out and plugging in a connector can be a couple of seconds. I simulated this as well and although the problem didn’t occur that often it still popped up from time to time.
First I tried to cause the interrupt with a relay (ms interval) – it was more difficult to generate the failure like this and its noise was disturbing – so I switched to a semiconductor: an NPN transistor inserted between the pins of the optical receiver and the the ADAV803. With this solution the PLL crashes within half a second for granted – in some of the cases with interrupt, sometimes without it.Based on the RxError and Lock flags the failure can be determined within a finite time frame even without interrupt, but in such cases the restart of the VCO is unnecessary and in vain.
Thank you for all of your help.
With best regards,
Gasper
