i would like to connect a clock generation?Distribution IC of ADI for connecting as a clock source. Which is the simple and variable frequency source that i can provide?
i chose AD9525 which requires a complex circuitry for itself.
Is this a clock source for the AD9912?
The AD9525 is the lowest jitter, and is a good choice. However, you much AC-couple this input.
Therefore, your circuit will have 180 ohm pull-down resistors on the AD9525 outputs, following by decoupling caps, and a 100 ohm resistor across the differential pair as close as possible to the system clock inputs.
