ADV7842 without extermal SDRAM

Hi,

the ADV7842 has an external SDRAM Interface.

 

It it said in the datasheet that:

EXTERNAL MEMORY REQUIREMENTS

The ADV7842 uses external SDRAM for 3D comb and frame synchronizer. The ADV7842 supports either SDR or DDR SD RAM.

 

Does this also mean that all other functions, especially using the part as a VGA/DVI to parallel converter do work without external DRAM

 

Thanks a lot.
