Overview
The AD9543BCPZ, manufactured by Analog Devices Inc., is a highly advanced clock synchronizer and jitter cleaner designed to support existing and emerging ITU standards for the delivery of frequency, phase, and time of day over service provider packet networks. This device features quad input and 10-output capabilities, with dual digital phase-locked loops (DPLLs) that significantly reduce timing jitter associated with external references. The AD9543BCPZ operates on a single 1.8 V power supply and is available in a 48-lead LFCSP (7 mm × 7 mm) package, suitable for a wide range of applications requiring precise clock synchronization and low jitter output signals.
