ADN2816 lock time

Hello guys,

 

i got a system picking up data at a more or less constant bit rate of 10Mbit/s. As recovery unit i thought about working with the ADN2816 which offers the desired rate.

 

At https://ez.analog.com/message/163320#163320 i found some answers belonging to my issue but it didnt answer it completely.

There is a value given in the datasheet for 10 Mb/s  with 40.0 ms acquisition time. Now if my data pauses for some time and starts over again, how long will it take to lock again? The VCO is working already in the right frequency band, thus i assume a locktime somewehere in the µs range.

Is it possible to make a more precisely prediction? Something that relys on given values in the datasheet would help my understanding.

 

Thanks in advance.

 

Mervell
