Im using MPC8548E processor with SYSCLK as 100MHz, CCB CLKYSCLK = 4:1 and CORE:CCB CLK = 3:1. so the CCB_CLK will be 400 MHz.I have planned to use DDR2 memory, what DDR2 frequency will the system support? Will it be 400MHz/2 = 200MHz?
Referring to the section 6.2.2 DDR SDRAM Output AC Timing Specifications of MPC8548E PowerQUICC™ III Integrated Processor Hardware Specifications the tMCK is 3.75ns does this mean that the processor will support a DDR2 with frequency 1/3.75ns = 266MHz??
Kindly help in this regard,
