Description

The ZL30342 is a member of a family of footprint-compatible devices offering the full range of features required for timing and synchronization across packet networks. This device focus on the Clock Recovery, Servo Mechanism and Clock Generation for Synchronization using IEEE-1588. They work seamlessly with Time Stamp solutions from all the major Switch/PHY NPU/CPU vendors. This single chip device offer both packet timing using IEEE-1588 Precision Time Protocol (PTP) and Synchronous Ethernet (SyncE) capable of driving the physical layer clock with the required very low jitter. The ZL30342 offers a full Stratum 3 DPLL, ideal for Timing Card applications and supports clock recovery over L2 and L3 networks for all wireless applications.
