Notes:
1.
Maximum rise/fall times are guaranteed at maximum specified
load.
Minimum rise/fall times are guaranteed at minimum specified
load.
Rise/fall times are specified with pure capacitive load as shown.
Testing is done with an additional 500Ω resistor in parallel.

Design Guidelines to Reduce EMI
1. Place series resistors and CI capacitors as close as possible to
the respective clock pins. Typical value for CI is 10pF. Series
resistor value can be increased to reduce EMI provided that
the rise and fall time are still within the specified values.
2. Minimize the number of “vias” of the clock traces.
3. Route clock traces over a continuous ground plane or over
a continuous power plane. Avoid routing clock traces from
plane to plane (refer to rule #2).
4. Position clock signals away from signals that go to any cables
or any external connectors.
