In Section 5.1, “Power-On Ramp Rate” added explanation that Power-On Ramp Rate is required to
avoid falsely triggering ESD circuitry.
In Table 13 changed required ramp rate from 545 V/s for MVREF and VDD/XVDD/SVDD to 3500 V/s
for MVREF and 4000 V/s for VDD.
In Table 13 deleted ramp rate requirement for XVDD/SVDD.
In Table 13 footnote 1 changed voltage range of concern from 0–400 mV to 20–500mV.
In Table 13 added footnote 2 explaining that VDD voltage ramp rate is intended to control ramp rate of
AVDD pins.

35/75 for RX_CLK duty cycle.
Added a reference to Revision 2.1.2.
Added Section 5.1, “Power-On Ramp Rate.”
