Jitter Specifications for the Input Reference Clocks
Both the reference clock inputs should meet the following jitter specification: the
refclk
10ps peak to peak, or 1.42ps RMS at 1e-12 BER, 1.22ps at 1e-16 BER.
You can set the frequencies of the reference clocks in the parameter editor, when
generating the HBM2 IP.

Note: The maximum user clock frequency describes the maximum clock frequency at which
the core <-> UIB interface can run. The actual core clock frequency depends on the
user interface requirements and timing closure in the Intel Quartus Prime Pro Edition
software.
