Description
Selects the polarity of the first post-tap for pre-
emphasis
Selects the magnitude of the first post-tap for pre-
emphasis.
Selects the polarity of the second post-tap for pre-
emphasis.
Selects the magnitude of the second post-tap for
pre-emphasis
Selects the slew rate of the TX output signal. Valid
values span from slowest to the fastest rate.
Enables the power-distribution network (PDN)
induced inter-symbol interference (ISI)
compensation in the TX driver. When enabled, it
reduces the PDN induced ISI jitter, but increases
the power consumption.
Selects the on-chip TX differential termination.
Enables the option to override the Intel-
recommended settings for one or more RX analog
parameters
Selects the RX high gain mode
the Continuous Time Linear Equalizer (CTLE).
Selects the DC gain of the Continuous Time Linear
Equalizer (CTLE) in high gain mode
Selects the AC gain of the Continuous Time Linear
Equalizer (CTLE) in high gain mode when CTLE is
in manual mode.
Selects the Variable Gain Amplifier (VGA) output
voltage swing.
Selects the on-chip RX differential termination.
