AD9142A LVDS data interface

Product Number: AD9142A

Hi!

In AD9142A, I am planning to use a single output only.

1) Is it possible to power down DAC2?

2) Is it possible to place consequent Q data w.r.t to DCI such as, Q0(Rising1), Q1(falling1), Q2(Rising2), Q3(Falling3). so that we can eliminate I data and increase throughput?

(eg: 400MHz DCI CLK with DDR should provide 800MSPS throughput if i am able to place Q data consequently without I data)

Thanks in-advance,

Deva

  • Hello,

    1) Is it possible to power down DAC2?

    Please see Table 27 in the datasheet.

    2) Is it possible to place consequent Q data w.r.t to DCI such as, Q0(Rising1), Q1(falling1), Q2(Rising2), Q3(Falling3). so that we can eliminate I data and increase throughput?

    There are only 2 modes for the AD9142A digital interface. Details are in page 23 of the datasheet.
