DAC38RF83: Multi-Device Coherency Using Internal VCO/PLL Clock Multiplication

Hi ldx,

Multi-device synchronization is possible with the internal PLL. What is the end application and are there any specific concerns or requirements that you can share publicly?

Thanks,
Eben.

Hi Eben,
Thanks for your quick reply.
The requirement is to design a simple beamforming communication system including 6 transceivers. The timing skew specification between them are less than 100ps。I plan to use LMK04828 to generate the clock and sysref for DACs and FPGA,and use DAC38RF83's internal PLL to generate DAC sample clock.Do you have any suggestions?
Thanks in advance!

Hi，
Has anyone tested DAC38RF83's multi-chip synchronization when using internal PLL?

HI,
Thanks a lot .
The synchronization has been done by using internal PLL or external high speed clock?
Hope for your timing skew result.
