8A34011 - Port Synchronizer

General Description

The 8A34011 is a port synchronizer for frequency and time/phase for equipment that uses packet based and physical layer based equipment synchronization.

Key Features

  • Eight independent timing channels.
  • Each can act as a frequency synthesizer, jitter attenuator, Digitally Controlled Oscillator (DCO), or Digital Phase Lock Loop (DPLL).
  • DPLL Digital Loop Filters (DLFs) are programmable with cut off frequencies from 17Hz to 22kHz.
  • Switching between DPLL and DCO modes is hitless and dynamic.
  • Generates output frequencies that are independent of input frequencies via a Fractional Output Divider (FOD).
  • Each FOD suppo.

Port Synchronizer for IEEE 1588 Frequency and Time/Phase 8A34011 Datasheet Overview The 8A34011 is a port synchronizer for frequency and time/phase for equipment that uses packet-based and physical layer-based equipment synchronization. The 8A34011 is a highly integrated device that provides tools to manage timing references, clock sources, and timing paths for IEEE 1588 and Synchronous Ethernet (SyncE) based clocks. The PLL channels can act independently as frequency synthesizers, jitter attenuators, Digitally Controlled Oscillators (DCO), or Digital Phase Lock Loops (DPLL). Typical Applications ▪ Core and access IP switches / routers ▪ Synchronous Ethernet equipment ▪ Telecom Boundary Clocks (T-BCs) and Telecom Time Slave Clocks (T-TSCs) according to ITU-T G.8273.
