Can you compare the advantages/disadvantages of the HM704x clock family vs the LTC695x family? They seem like very similar parts.
ADI offers the two lowest jitter JESD204B/C multi-output clock generation devices on the market in the <4.5GHz frequency range. While these devices are very similar in some respects, there are some fairly significant differences that may make one device better than the other for your application. These differences are listed in the table below.
For generating large clock trees. Both parts have a companion clock distribution device, HMC7043 and LTC6953, that allow for synchronizing clocks and SYSREFs across multiple chips.
The HMC7044 and HMC7043 family have specialized synchronization functions that allow for multiple chip synchronization of an unlimited number of clock and SYSREF signals.
Likewise, the LTC6952 and LTC6953 family have specialized synchronization functions that allow for multiple chip synchronization of an unlimited number of clock and SYSREF signals.
For multiple chip synchronization, the synchronization functions between the HMC7044/43 and LTC6952/53 families are different. In other words, connecting a LTC6952 output to a HMC7043 input (or a HMC7044 output to a LTC6953 input) will not synchronize the outputs of both chips as desired.
Refer to the product pages and datasheets for more information on multiple chip synchronizations:
I'd like to ask you a question that whether the LTC6952's output can be the input of AD9528's VCO?
Yes, if you AC couple the signal, as The LTC6952's output common mode is different than the AD9528 VCXO pin's input common mode requirement.
I'm curious why this combination is of interest. Are you trying to take advantage of the AD9528's jitter clean-up loop (PLL1) or some other feature? The reason I ask, is I am trying to figure out if you have the best combination of parts for what you are trying to achieve.
Thanks for your answer! The reason why I pick LTC6952 is that it can operate in very high frequency. As for AD9528,is I want to use AD9528 for AD9371. In the meanwhile,I want to make all clocks in my system operate from a same sourse.So,I use LTC6952 as the sourse of AD9528.
