Application Information
Input Reference
When operating with a crystal input reference, do not
apply a switching signal to REF_IN.
Crystal Layout
Keep the layers under the crystal as open as possible
and do not place switching signals or noisy supplies
under the crystal.
Crystal load capacitance is built inside the die so no
external capacitance is needed. See the Selecting a
Quartz crystal for the Clockworks Flex I Family of
Precision
Synthesizers application
note for further
details.
Contact Micrel’s HBW applications group if you need
assistance on selecting a suitable crystal for your
application at: hbwhelp@micrel.com.
HCSL Outputs
HCSL outputs are to be terminated with 50
Ω to V
SS.
For
best performance load all outputs. If you want to AC-
couple or change the termination, contact Micrel’s
application group at: hbwhelp@micrel.com.
