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.
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.
These are the only commercially available single chip devices to 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.
ITU-T G.8262 System Timing Cards which support 1 GbE and 10 GbE interfaces
Telcordia GR-253 Carrier Grade SONET/SDH Stratum 3 System Timing Cards
System Timing Cards which supports ITU-T G.781 SETS (SDH Equipment Timing Source)
Integrated basestation reference clock for air interface for GSM, WCDMA, LTE and WiMAX macro, micro or
femtocells
Mobile Backhaul NID, edge router or access aggregation node
