AD9146 LVDS Input Rate,DCI,fINTERFACE, and fDAC ?

Hi,all

I am confused the relation between "LVDS Input Rate" and "fDAC".

In the AD9146 datasheet,

Table 5. Maximum Rate (MSPS) with DVDD and CVDD Supply Regulation

Figure 30. Timing Diagram for Byte Mode

Figure 30. Timing Diagram for Byte Mode

In byte mode case, and 1× Interpolation Factor,

What is the fINTERFACE (MSPS) ? Is it the DCI(1200MSPS), or DCI(600MSPS) by DDR(600MSPS*2) ?

Then, Is FRAME rate 600MSPS ?, and why is the fDAC max, 300MSPS ?

Best Regards,
