    Thread Summary
    
                The user inquired about the initial lock time and reacquisition time of a 1Gbps burst mode data stream with 50uS gaps using the ADN2819 CDR. The support engineer clarified that the ADN2819 is not suitable for burst mode applications and is designed for continuous mode telecomm and datacomm. No specific reacquisition time was provided.

    What is the initial lock time with valid serial random data stream?
    
 
    My application uses 1Gbps data that comes in bursts with gaps of 50uS.  After first acquisition, how long does the device take to reacquire the clock?  I'm looking to see how long the training sequence has to be.
    
 
    thanks,
