“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.

Supply noise testing was done with minimum capacitors (as shown on Figure 37 and Figure 38) 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.
