AM3358: Queries regarding DDR3L on custom board

Part Number: AM3358

Hi,

We have some doubts on choosing and interfacing a suitable DDR3L memory for a custom board with AM3358 processor.

1. AM335x supports min frequency of 303 MHz and max frequency of 400 MHz. Does this mean I can operate the DDR3 at ANY frequency in between 303 MHz and 400 MHz ? Or it is either 303 MHz OR 400 MHz?

2. If my DDR operating frequency is not finalized at pre-layout stage, what frequency do you recommend using for pre-layout SI analysis and PCB design? 303 MHz or 400 MHz?

3. Does Table 7-60 mean that I need a DDR of speed grade higher than 1600 to operate at 400 MHz? If I have a DDR3-1333, am I limited to 303 MHz?
