Zarlink Semiconductor Inc.
1.0 Functional Description
The ZL30119 SONET/SDH Line Card Synchronizer is a highly integrated device that provides timing and
synchronization for network interface cards. It incorporates two independent DPLLs, each capable of locking to one
of eight input references and provides a wide variety of synchronized output clocks and frame pulses.
1.1 DPLL Features
The ZL30119 provides two independently controlled Digital Phase-Locked Loops (DPLL1, DPLL2) for clock and/or
frame pulse synchronization. Table 1 lists the feature summary for both DPLLs.

Loop Bandwidth
User selectable: 14 Hz, 28 Hz, or
wideband
1
(890 Hz / 56 Hz / 14 Hz)
1. In the wideband mode, the loop bandwidth depends on the frequency of the reference input. For reference frequencies equal to or
greater than 64 kHz, the loop bandwidth = 890 Hz. For reference frequencies equal to or greater than 8 kHz and less than 64 kHz, the
loop bandwidth = 56 Hz. For reference frequencies equal to 2 kHz, the loop bandwidth is equal to 14 Hz.
