(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; the device should not be operated beyond such conditions.

(1) Supply noise testing was done with minimum capacitors (as shown on Figure 32 and Figure 33 on the PCB. A sinusoidal signal is AC
coupled to the V_DDn (1.8V) supply with amplitude = 25 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 1 MHz. The Des on the
other hand shows no error when the noise frequency is less than 750 kHz.
