MT9046 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.
