Overview: 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.
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.8273.2 ▪ 10Gb, 40Gb, and 100Gb Ethernet interfaces ▪ Central Office Timing Source and Distribution ▪ Wireless infrastructure for 4.
