Our team is looking for a 10GE switch with 1588 transparent clock support. As we see, X670-G2 should be able to do this. However we are a bit confused by the statement in the Data Sheet:
"The X670-G2 offers Boundary Clock (BC), Transparent Clock (TC), and Ordinary Clock (OC) for synchronizing phase and frequency and allowing the network and the connected devices to be synchronized down to microseconds of accuracy over Ethernet connection."
The microsecond accuracy would be catastrophic in 1588. Each nanosecond counts here.
The "correction" field in PTP packet provides picosecond precision.
So, the question is whether microseconds is only a typo and X670-G2 really supports 1588 TC with a sub-nanosec precision?
We need the switch in a 10GE timing measurement lab, so a high accuracy is a MUST.
Thank you in advance.
