Precision 1-18 Clock Buffer
Figure 1. Clock Waveforms
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.
Testing is done with an additional 500-ohm 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.
