DDC264: DDC264CK about the Analog Power and Data Rate

Part Number:DDC264

Hi Sir：

     I noticed that the DDC264C  and  DDC264CK，They are different voltage requirements for Analog Power. May I  think that. higher precision of power supply  support better data Rate. For DDC264CK if my power is 4.85 to 5.15. It can work. but maybe the Data Rate can not up to 6K.
