AD9142A VCO

Hi

I'm a DFAE in Japan. Our customer uses AD9142A. When fVCO is set 2.00GHz, is there anything you care about? He uses Automatic mode. We feel that there is no margin at 2.00GHz compared to 2.07GHz.

Regards

Hiroyuki

  • Hello Hiroyuki,

    Thank you for your interest in AD9142A. 2GHz is within the optimal operating range of fVCO. Please take note in selecting a ref clk frequency, N1 & N2 values so that desired DACCLK frequency can be synthesized and the VCO output frequency is in the correct range. 

    Also sharing here a link  that might be useful in your evaluation.

    Many Thanks,

    Lorenz
