System Design Information
Another useful equation is:
where:
Ifw = Forward current
Is = Saturation current
Vd = Voltage at diode
Vf = Voltage forward biased
VH = Diode voltage while IH is flowing
VL = Diode voltage while IL is flowing
IH = Larger diode bias current
IL = Smaller diode bias current
q = Charge of electron (1.6
× 10 –19 C)
n = Ideality factor (normally 1.0)
K = Boltzman’s constant (1.38
× 10–23 Joules/K)
T = Temperature (Kelvins)
The ratio of IH to IL is usually selected to be 10:1. The above simplifies to the following:
VH – VL = 1.986 × 10
–4
× nT
Solving for T, the equation becomes:
21 System Design Information
This section provides electrical and thermal design recommendations for successful application of the
MPC8533E.
21.1
System Clocking
This device includes six PLLs:
The platform PLL generates the platform clock from the externally supplied SYSCLK input. The
frequency ratio between the platform and SYSCLK is selected using the platform PLL ratio
configuration bits as described in Section 19.2, “CCB/SYSCLK PLL Ratio.”
The e500 core PLL generates the core clock as a slave to the platform clock. The frequency ratio
between the e500 core clock and the platform clock is selected using the e500 PLL ratio
configuration bits as described in Section 19.3, “e500 Core PLL Ratio.”
The PCI PLL generates the clocking for the PCI bus.
