AD9781 dual-port and interleaved LVDS inputs

Hi,

I would like to understand more detail in AD9781 LVDS.

In AD9781 datasheet, LVDS inputs with dual-port or optional interleaved single-port operation:

Might I know if ADI have more detail regarding to 2 different port operation? Such as Timing diagram.

We have two different set of input and output.

I assume the following is the interleaved single-port.

Might I know how is the dual-port operation? AD9781 only has D13-D0 data pin.

I am not sure if AD9781 can be dual port input in parallel.

Please kindly advise. Appreciate your help in advance.

  • Hello ,

    The AD9783/81/80 DAC family only has a single LVDS port which receives multiplexed/interleaved I and Q data words. This family is based off of the AD9747/46/45/43 DAC family which has the dual-port and interleaved single-port options. The wording of the particular feature might have been overlooked on the AD9783/81/80 datasheet which is now lined up for revision. Thank you for pointing this out.
