(1) The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as
otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and
are not guaranteed.
(2) Typical values represent most likely parametric norms at V_DD33 = 3.3V, V_DDIO = 1.8V or 3.3V, Ta = +25 degC, and at the Recommended
Operation Conditions at the time of product characterization and are not guaranteed.
(3) Current into device pins is defined as positive. Current out of a device pin is defined as negative. Voltages are referenced to ground
except V_OD and ΔV_OD, which are differential voltages.Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal
signal is AC coupled to the supply pins with amplitude = 100 mVp-p measured at the device V_DD33 and V_DDIO pins. Bit error rate testing
of input to the serializer and output of the deserializer with 10 meter cable shows no error when the noise frequency is less than 50MHz.
