(1) Supply noise testing was done with minimum capacitors (as shown on Figure 44 Figure 46) on the PCB. A sinusoidal signal is AC
coupled to the VDDn (1.8V) supply with amplitude = 25 mVp-p measured at the device VDDn 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 1 MHz. The Des on the
other hand shows no error when the noise frequency is less than 750 kHz.

(1) The Electrical Characteristics tables list ensured 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 ensured.
(2) 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.
(3) Typical values represent most likely parametric norms at 1.8V or 3.3V, TA = +25°C, and at the Recommended Operation Conditions at
the time of product characterization and are not specified.
