AD9544BCPZ

AD9544 is a 10-output, dual DPLL, 1pps synchronizer and jitter cleaner. The 10-clock output of the synchronized to any one of up to four input references. The digital phase-locked loops (DPLLs) reduce the timing jitter associated with the external references. The digitally controlled loop and holdover circuitry continuously generate a low jitter output signal, even when all reference inputs fail. Application includes SyncE and GPS synchronization and jitter clean-up, optical transport networks (OTN), SDH, and macro and small cell base stations, OTN mapping/demapping with jitter cleaning, small base station clocking, including baseband and radio stratum 2, Stratum 3e, and Stratum 3 holdover, jitter clean-up, and phase transient control JESD204B support for analog-to-digital converter (ADC) and digital-to-analog converter (DAC) clocking, cable infrastructures and carrier Ethernet.
