In DM8168 the DDR controller clock is (SYSCLK8)/2 = 400MHz. But, it is specified in the datasheet that DDR3 interface clock is 800MHz.
Can anybody clarify what is the interface clock at which DDR3 runs? Is it 400MHz or 800MHz?
And if it is 800MHz how is this clock derived?
Does anyone has the DM8168 DDR3 controller datasheet?
If yes, can you please share it?
