    How does ADN2812 jitter could not tolerate 0.067 UIp-p synchronizing with 15 MHZ data stream; could ADN2913 tolerate the 0.067 UIp-p at 15MHZ?

        Thank you for your response Dongfeng.
        
 
        Your Q. 1. What is the industry application at this rate? Answer:The
        
 
        aplication is a tape transport for linear tape open technology (LTO).
        
 
        Present design runs from 4 MHZ to 24 MHZ. So, I am thinking of evaluating
        
 
        the ADN2913 if it can tolerate more jitter than ADN2812.
        
 
        2. What is the jitter spectrum defined for this 15 Mbps
        
 
        application?Answer:I don't know the spectrum but I measured the jitter in
        
 
        the time domain with an oscilloscope to be 4.5 ns peak to peak period
        
 
        jitter and calculated 4.5ns/(1/15MHZ) = 0.067 UI. see picture in attachment.
        
 
        Your comment to scale the the jitter tolerance of OC-3 to the 10 th
        
 
        harmonic is OK . I think you meant 130KHZ instead of 1.3KHZ.
        
 
        Your Q: Does the 15Mbps signal source have strong jitter component at KHZ?
        
 
        Answer: Yes, at about 50 KHZ. (the rotation of a capstan motor).
        
 
        I already evaluated the ADN2812 and it could not maintain lock.
        
 
        Do you know if the ADN2913 transfer bandwidth and the sample phase
        
 
        adjustent can help to tolerate more jitter than the ADN2812?
        
 
        Thanks,
