Features
Recovers and transmits network synchronization
over Ethernet, IP and MPLS Networks
Simultaneously supports both the Synchronous
Ethernet and the IEEE1588 industry standard timing
protocols
Capable of server, client and repeater operation
Integrates two separate digital phase locked loops,
with hitless switching between packet and electrical
clock references
Primary DPLL meets Stratum 3/SONET quality
Targeted for synchronization distribution to better
than ITU-T G.8261, G.823, G.824 and ANSI T1.101
synchronization interface standards
Average frequency accuracy better than ±10 ppb
Aligns to a low frequency input signal at server
(e.g., 1 Hz) with targeted accuracy better than ±1 μs
Recovers clocks from two independent servers, with
hitless switching between packet streams for
redundancy
Supports holdover if the server stream is lost
Accepts eight input references, and up to three
associated low frequency alignment or framing pulses
Generates up to four separate output clocks at
frequencies between 8 kHz and 100 MHz
