SOFTWARE
• C99 source code distribution, supporting POSIX-based Operating Sys-
tems (OSs) such as Linux
• IEEE 1588 compliant Precision Time Protocol (PTP) stack
• Abstraction interface supports user-supplied IEEE 1588 compliant Pre-
cision Time Protocol (PTP) stack
• Reference trackers filter packet synchronization noise from IEEE 1588
unaware networks
HARDWARE
• Synchronization Management Unit (SMU) provides tools to manage
physical layer and packet based synchronous clocks for IEEE 1588
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 PLLs can be configured as Digitally Controlled Oscillators
(DCOs) for IEEE 1588 clock synthesis
• Generates G.8262 compliant SyncE clocks
• Fractional-N input dividers support a wide range of reference frequen-
cies
• Locks to 1 pulse per second (PPS) references from GPS based sources
• Loads configuration from an external EPROM after reset
