Application Information
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.
LVDS Outputs
LVDS outputs are to be terminated with 100 across Q
and /Q. For best performance, load all outputs. Outputs
can be DC or AC-coupled.
HCSL Outputs
HCSL outputs are to be terminated with 50 to VSS. For
best performance, load all outputs. For AC-coupled or to
change the termination, contact Micrel’s application
group: hbwhelp@micrel.com.
