Overview

The 82V3398 is an integrated, single-chip solution for the Synchronous Equipment Timing Source (SETS) for Stratum 3, 4E, 4, SMC, EECOption1, EEC-Option2 clocks in SONET/SDH/Synchronous Ethernet equipment, DWDM, and wireless base stations. The device consists of a high-quality and configurable DPLL to provide a system clock for node timing synchronization within a SONET/SDH/Synchronous Ethernet network.
