ADIsimPLL Support
The ADF4193 loop filter design is supported on ADIsimPLL
v2.7 or later. Example files for popular applications are available
for download from the applications section of the ADF4193
product page.
Also available is a technical note (ADF4193-TN-001) that
outlines a loop filter design procedure that takes full advantage
of the new degree of freedom in the filter design that the
differential amplifier and loop filter switches provide.
