8.9.1

Clock Input Bandwidth (ClkIn_BW[2:0])

Sets the minimum loop bandwidth when locked to CLK_IN.

Note:

In order to guarantee that a change in minimum bandwidth takes effect, these bits must be set

prior to acquiring lock (removing and re-applying CLK_IN can provide the unlock condition necessary to

initiate the setting change). In production systems these bits should be configured with the desired values

prior to setting the EnDevCfg bits; this guarantees that the setting takes effect prior to acquiring lock.
