For DC input levels, see section DC Input and Output Levels.
Note: Generally, Hysteresis = OFF is recommended. In extremely high noise systems with degraded
reference clock input, Hysteresis = ON may improve results.
5.4.4 Transmier Performance
The following tables describe performance of the transmitter.

Thevenin
impedance is
calculated
based on
independent P
and N as
measured at
50% of VDDI.
For 50Ω/75Ω/
150Ω cases, the
nearest
supported
values of
40Ω/60Ω/120Ω
are used.

Note: All pull-ups are disabled at power-up to allow hot plug capability.
The following tables describe the PolarFire transceiver user interface clocks.
Note: Until specied, all modes are non-deterministic. For more information, see PolarFire Family
Transceiver User Guide.
