Synchronization Management Unit for IEEE 1588 and 10G/40G/100G Synchronous Ethernet
82P33831
Datasheet
HIGHLIGHTS
• Synchronization Management Unit (SMU) provides tools to manage physical layer and packet based synchronous clocks for IEEE 1588 / PTP Telecom Profile applications
• Supports independent IEEE 1588 and Synchronous Ethernet (SyncE) timing paths
• Combo mode provides SyncE physical layer frequency support for IEEE 1588 Telecom Boundary Clocks (T-BC) and Telecom Time Slave Clocks (T-TSC) per G.8273.2
• Digital PLL 1 (DPLL1) and DPLL 2 can be configured as Digitally Controlled Oscillators (DCOs) for PTP clock synthesis
• DCO frequency resolution is [(77760 / 1638400) * 2^-48] or ~1.686305041e-10 ppm
• DPLL1 and DPLL2 generate G.
