(1) Specification is verified by design and is not tested in production.
(2) Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC coupled to the V_DDn (1.8V) supply with
amplitude = 100 mVp-p measured at the device V_DDn pins. Bit error rate testing of input to the Ser and output of the Des with 10 meter
cable shows no error when the noise frequency on the Ser is less than 750 kHz. The Des on the other hand shows no error when the
noise frequency is less than 400 kHz.

(1) The Electrical Characteristics tables list verified 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
verified.
(2) Typical values represent most likely parametric norms at V_DD = 3.3V, Ta = +25 degC, and at the Recommended Operation Conditions at
the time of product characterization and are not verified.
(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 VOD, ΔVOD, VTH and VTL which are differential voltages.
(4) Specification is verified by design and is not tested in production.
(5) Specification is verified by characterization and is not tested in production.
