Description
The MT9046 T1/E1 System Synchronizer contains a
digital phase-locked loop (DPLL), which provides timing
and synchronization signals for multitrunk T1 and E1
primary rate transmission links. The device has
reference switching and frequency holdover capabilities
to help maintain connectivity during temporary
synchronization interruptions.
