What is the 10-bit DDR mode limitation for ADV7612/ADV7511

In the ADV7612/ADV7511 datasheets it is said, that:

"DDR mode is only supported only up to 50 MHz (an equivalent to data rate clocked 100 MHz clock in SDR mode"

But what SDR mode is meant here - 10-bit or 20 bit?

Because of this uncertainty please answer:

1). Is DDR mode supported for 10-bit 1920x1080x60i  ( 1,485 Gbit/s mode ) in ADV7612/ADV7511?

2). Is DDR mode supported for 10-bit 1920x1080x60p ( 2,97 Gbit/s mode ) in ADV7612/ADV7511?

 

It seems to me, that the answer to the both questions is NO.

Because for both modes DDR-mode clock exceeds 50 Mhz.

That means , that DDR mode is for SD only ....
