AD9545BCPZ

AD9545 is a quad input, 10-output, dual DPLL/IEEE 1588, 1pps synchronizer and jitter cleaner. It supports existing and emerging international telecommunications union (ITU) standards for the delivery of frequency, phase, and time of day over service provider packet networks, including ITU-G.8262, ITU-T G.812, ITU-T G.813, ITU-T G.823, ITU-T G.824, ITU-T G.825, and ITU-T G.8273.2. It is used in applications such as global positioning system (GPS), PTP (IEEE 1588), and synchronous Ethernet (SyncE) jitter clean-up and synchronization, optical transport networks (OTN), synchronous digital hierarchy (SDH), and macro and small cell base stations, 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, carrier Ethernet.
