1. The clock delay from the input of the PLL clock to the input of any DDR2 SDRAM or register will be set to 0ns (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 the PLL feedback path clocks are located as close to the input pin of the PLL as possible.
