... M9999-073008 hbwhelp@micrel.com or (408) 955-1690 Lock Detect The SY87700V contains a link fault indication circuit which monitors the integrity of the serial data inputs. If the received serial data fails the frequency test, the PLL will be forced to lock to the local reference clock. This will maintain the correct frequency of the recovered clock output under loss of signal or loss of lock conditions ...
