Notes: 1. The clock delay from the input of the PLL clock to the input of any SDRAM or register willl
be set to 0 ns (nominal).
2. Input, output and feedback clock lines are terminated from line to line as shown, and not
from line to ground.
3. Only one PLL output is shown per output type. Any additional PLL outputs will be wired
in a similar manner.
4. Termination resistors for feedback path clocks are located after the pins of the PLL.
