Data Sheet

Zarlink Semiconductor Inc.
The output clocks and frame pulses derived from the low jitter APLL are always synchronous with DPLL1, and the
clocks and frame pulses generated from the programmable synthesizers can be synchronized to either DPLL1 or
DPLL2. This allows the ZL30120 to have two independent timing paths.
Figure 6 - Output Clock Configuration
The supported frequencies for the output clocks and frame pulses are shown in Table 4.
