Does the ADV202/212 tile the input if my input image is larger than the maximum specified?

No. The user has to tile the input before compression if the input image size exceeds the maximum allowed image size of 1.048 Msamples/image.

Image width must stay below a maximum of 2048 samples or 4096 samples, depending which compression mode [5/3 or 9/7] is used. Refer to the datasheet for more detail on tile width limitations.
