The 8A34004 is a Synchronization Management Unit (SMU) for packet based and physical layer based equipment synchronization.

Two 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 legacy SONET/SDH and PDH requirements.
DPLL Digital Loop Filters (DLFs) are programmable with cut off frequencies from 12µHz to 22kHz.
DPLL/DCO channels share frequency in.
