ZL30407
Data Sheet
The ZL30407 operates in NORMAL (LOCKED), HOLDOVER and FREE-RUN modes to ensure that in the
presence of jitter, wander and interruptions to the reference signals, the generated clocks meet international
standards. The filtering characteristics of the PLL are hardware or software selectable and they do not require any
external adjustable components. The ZL30407 uses an external 20 MHz Master Clock Oscillator to provide a stable
timing source for the HOLDOVER operation.
The ZL30407 operates from a single 3.3 V power supply and offers a 5 V tolerant microprocessor interface.
