How do the PLLs in the AD951x parts compare to other ADI PLLs?
The design of the PLL core used on the AD9510/AD9511 began with the ADF4106. There were modifications made to the design to suit it better for its role in the clock ICs. There are some configuration differences between the PLL on the AD9510/11 and the ADF4106, and its maximum VCO frequency is 1600 MHz rather than 6 GHz. But the performance characteristics of the ADF4106 were maintained, so that the PLL on the AD9510/11 provides performance nearly identical to the ADF4106.
