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 R
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.
Testing is done with an additional 500 resistor in parallel.
