LTC2000 DAC Clock Driver

Question

Hi 
 I am FAE in Japanese Distributor. 
 Our customer will use LTC2000 at CKP/N=200MHz and DCKIP/N=100MHz 
 Figure 13 shows DAC Clock with the LTC6946. 
 But RF output frequency of LTC6946 is from 370MHz to 6.39GHz. 
 He thinks to use ADN4650 as DAC Clock Driver IC. 
 Does ADN4650 work well the following circuit? 
 
 Could you recommend other DAC Clock Driver IC? 
 Best regards 
 N.Kokubo

I am not familiar with that part, but it seems like 120 would be ok.)

The LTC6950 would be a good clock driver for the LTC2000. It would also work with the ADN4650.

ADIApproved · Answer

Yes you can AC couple.

ADIApproved · Answer

Strictly speaking, yes that is true. 250mV is 50mV less than the 300mV minimum of the LTC2000
