(1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating
Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.

(1) Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC coupled to the VDDn (1.8V) supply with
amplitude = 100 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 750 kHz. The Des on the other hand shows no error when the
noise frequency is less than 400 kHz.
