Questions for your ADN2812

Dear Sir/Madam,

 

I need your help.

 

I am just studing with your Data Recovery IC ADN2812.

I would like to set the datarate to 100Mbps.
So I input 12.5MHz clock or 100MHz clock to REFCLK, and confirm the drive, but I cannot catch the good result.

 

Question-1:
When I set REFCLK to 100Mbps, which should I set CLRLA[7..6] to 10 or 11?

Question-2:
As for the following my set-up, is this no probrem?
  When REFCLK=12.5MHz, CTRLA[7..0]=00001101
  When REFCLK=100MHz, CTRLA[7..0]=10001001

 

Please give me your good comment.

 

Thanks Kaos
