DAC38RF80: DAC38RF80 VCO?

HENRY JUNG

Part Number: DAC38RF80

Dears.

We are developing DAC38RF80.

In the data sheet, the VCO range is from 5.24GHz to 6.72GHz.

I want to use the VCO at 6.63552 GHz.

Is it available as specified in the datasheet?

Can I use VCO at 6.63552Ghz in DAC38RF8xEVM?

If so, What is the way?

Thank you.

    Hi,

    It is possible to run the DAC VCO frequency at 6.63552 GHz if you provide an appropriate reference clock frequency. You can select the reference frequency (Fref) as any of the follwing: 

    Fref = N*6.63552/(M*4), N,M are the PLL N and M dividers and M should be greater than 3.

    Thanks,

    Eben.
