(1) Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC coupled to the V
DD33
and V
DDIO
supplies
with amplitude = 100 mVp-p measured at the device V
DD33
and V
DDIO
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 50MHz. The Des on the other hand shows no
error when the noise frequency is less than 50 MHz.

(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) 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 ensured.
(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 and ΔVOD, which are differential voltages.
