MT9045 Datasheet (Zarlink Semiconductor) - T1/E1/OC3 System Synchronizer

MT9045, T1/E1/OC3 System Synchronizer

The MT9045 T1/E1/OC3 System Synchronizer contains a digital phase-locked loop (DPLL), which provides timing and synchronization signals for multitrunk T1 and E1 primary rate transmission links and STS-3/OC3 links.

The MT9045 generates ST-BUS clock and framing signals that are phase locked to either
