Inadvertent Assertion of LOL During Clock Switching
4. Inadvertent Assertion of LOL During Clock Switching
Description
Inadvertent assertion of LOL during clock switching between two clocks that are the same exact frequency.
Impacts
If LOL is asserted, the device may enter fastlock LBW mode, causing undesirable frequency transients.
Workaround
Relaxing the LOL set and clear thresholds will eliminate this issue. ClockBuilder Pro, beginning with version v1.1, implements these
settings as the defaults.
Resolution
This erratum was addressed, beginning with ClockBuilder Pro v1.1. Users are strongly encouraged to always use the latest ClockBuild-
er Pro revision.
