(1) Supply noise testing was done with minimum capacitors 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.
