82V3398 Block Diagram


Synchronous Ethernet WAN PLL

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


  • Integrated single-chip solution for Synchronous Equipment Timing Source, including Stratum 3, 4E, 4, SMC, EEC-Option 1 and EEC-Option 2 Clocks
  • Hitless reference switching to minimize DPLL output phase transients
  • Programmable input-to-output phase offset adjustment
  • Provides 6 output clocks from 1 Hz (1PPS) to 644.53125 MHz
  • Provides 6 input clocks from 1 Hz (1PPS) to 625 MHz
  • Internal DCO controlled by an external processor for IEEE-1588 clock generation
  • Free- Run, Locked and Holdover modes
  • Automatic hitless selected input clock switch on clock failure
  • 2 kHz, 4 kHz, 8 kHz, or 1PPS frame sync input, 2 kHz, 8 kHz, or 1PPS frame sync output 
  • Output clocks for BITS, GPS, 3G, GSM, etc.
  • PECL/LVDS and CMOS input/output technologies
  • Master/Slave feature for system protection against single chip failure
