8A34005 - Synchronization Management Unit

General Description

The 8A34005 is a Synchronization Management Unit (SMU) for packet based and physical layer based equipmen

Key Features

  • Four independent timing channels.
  • Each can act as a frequency synthesizer, jitter attenuator, Digitally Controlled Oscillator (DCO), or Digital Phase Lock Loop (DPLL).
  • DPLLs generate telecom compliant clocks.
  • Compliant with ITU-T G.8262 for Synchronous Ethernet.
  • Compliant with ITU-T G.8262.1 for enhanced Synchronous Ethernet.
  • Compliant with legacy SONET/SDH and PDH requirements.
  • DPLL Digital Loop Filters (DLFs) are programmable with cut off frequen.

Synchronization Management Unit 8A34005 Datasheet Overview The 8A34005 Synchronization Management Unit (SMU) 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). Optional IEEE 1588 software is available under license from Renesas for use with the 8A34005. The software includes clock recovery servos that can be used with the Linux PTP IEEE 1588 protocol stack or with other IEEE 1588 protocol stacks.
