MT9042C Multitrunk System Synchronizer

The MT9042C Multitrunk 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 MT9042C generates ST-BUS clock and framing signals that are phase locked to either a 2.048MHz, 1.544MHz, or 8kHz input reference. The MT9042C is compliant with .
