IEEE-1588 eCPRI Programmable Synchronization Management Unit
[Figure 3, callout 46]
The 8A34001 synchronizaon management unit (SMU) provides tools to manage ming
references, clock sources, and ming paths for IEEE 1588 and Synchronous Ethernet (SyncE)
based clocks. The PLL channels can act independently as frequency synthesizers, jier
aenuators, digitally controlled oscillators (DCO), or digital phase lock loops (DPLL). The
following block diagram can aid in quickly determining the overall clock tree for the 8A34001
(U219). See schemac pages 90-91 for details. For more details on programming and controlling
the 8A34001, see the Renesas/Integrated Device Technology, Inc. (IDT) website and data sheet.
