Notes:
1. Maximum rise/fall times are guaranteed at maximum specified load for each type of output buffer.
2. Minimum rise/fall times are guaranteed at minimum specified load for each type of output buffer.
3. Rise/fall times are specified with pure capacitive load as shown. Testing is done with an
additional 500
resistor in parallel.

Minimum and Maximum Expected Capacitive Loads
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.
