Description
The ZL30409 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 ZL30409 generates ST-BUS clock and framing
signals that are phase locked to either a 19.44 MHz,
2.048MHz, 1.544MHz, or 8kHz input reference.
