Minimum and Maximum Expected Capacitive Loads
Notes:
1. Maximum rise/fall times are guaranteed at maximum specified load.
2. Minimum rise/fall times are guaranteed at minimum specified load.
3. Rise/fall times are specified with pure capacitive load as shown.
Design Guidelines to Reduce EMI
1. Place series resistors and CI capacitors as close as possible to the respective clock pins. Typical value
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
4. Position clock signals away from signals that go to any cables or any external connectors.
are still within the specified values.
clock traces from plane to plane (refer to rule #2).
Testing is done with an additional 500
for CI is 10pF. Series resistor value can be increased to reduce EMI provided that the rise and fall time
