ZL30110

In Production

The ZL30110 clock rate conversion digital phase-locked loop (DPLL) provides accurate and reliable frequency conversion. The ZL30110 generates a range of clocks that are either locked to the input reference or locked to the external crystal or oscillator. In the locked mode, the reference input is continuously monitored for a failure condition. In the event of a failure, the DPLL continues to provide a stable free running clock ensuring system reliability.
