Note:
1. Caution: The platform clock to SYSCLK ratio and e5500 core to SYSCLK ratio settings must be chosen such that the
2. The memory bus clock speed is half the DDR3/DDR3L data rate. DDR3/DDR3L memory bus clock frequency is limited to
3. The local bus clock speed on LCLK[0:1] is determined by the platform clock divided by the local bus ratio programmed in
4. The e5500 core can run at e5500 core complex PLL/1 or PLL/2. With a minimum core complex PLL frequency of 1333 MHz,
5. In synchronous mode, the memory bus clock speed is half the platform clock frequency. In other words, the DDR data rate
6. In asynchronous mode, the memory bus clock speed is dictated by its own PLL.
7. The PME runs synchronously to the platform clock, running at a frequency of platform clock/2.
8. For the FMan: 300 MHz is the minimum to support 1 G. 450 MHz is the minimum to support 10 G. 500 MHz is the minimum
resulting SYSCLK frequency, e5500 (core) frequency, and platform clock frequency do not exceed their respective
maximum or minimum operating frequencies.
min = 400 MT/s.

this results in a minimum allowable e5500 core frequency of 667MHz for PLL/2.
is the same as the platform frequency. If the desired DDR data rate is higher than the platform frequency, asynchronous
mode must be used.
to support 10 G with PCD. 600 MHz is the minimum to support 12 G (10 G + 2*1 G) with PCD.
