LMK5B33414 Overview
The LMK5B33414 is a high-performance network synchronizer and jitter cleaner designed to meet the stringent requirements of ethernet-based networking applications with < 5-ns timing accuracy (class D). The network synchronizer integrates three DPLLs to provide hitless switching and jitter attenuation with programmable loop bandwidth and no external loop filters, maximizing flexibility and ease of use. Each DPLL...
