DAC5688: About polarity of internal differential input

Part Number: DAC5688

On the DAC5688 Datasheet page-38; Figure 42, I look like that differential output is inverting, please see attached below.

Is CLKO_CLK1 input take care of polarity?

For example, should CLKO_CLK1 input set to inverting polarity in order to match internal differential input?

Hi Satoshi,

As long as customers is following the setup and hold timing requirement for each clocking mode they should be fine. They don't have to worry of the polarity of CLKO_CLK1.
