The Zynq Ult MPSoC recovers clock information from IEEE 1588 packets on the SFP
ports. This clock is fed to an IDT 8A34001 Network Synchronizer which in turn cleans up noise
and feeds this clock back to the Zynq Ult MPSoC. When the reference clocking to the
network synchronizer disappears, it enters holdover mode. The holdover time for the card is
expected to be in the range of four hours with a phase deviation of 1.5μs. During holdover, the
reference clock from the Network Synchronizer is derived from a high accuracy OCXO.
