8A34005 Synchronization Management Unit

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

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 8A340.

8A34005 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
