Part Number: DAC38RF82

how does the performance of this part differ when using the internal PLL vs clocking it with the LMK2592?

Clint,

We have no data with the DAC being clocked by the LMK2592. If you would like, I can send some performance data with the DAC being clocked by the PLL. The performance should be better when using the LMK device, but we have not tried it.

Regards,

Jim

Performance data when being clocked by the internal PLL would be great! Thanks

Clint,

This data compares several AC specs of the internal NCO used to generate an output tone with the PLL vs an external clock from a signal generator.
