Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC-coupled to the VDD33 and VDDIO supplies with amplitude = 100 mVp-p measured at the device VDD33 and VDDIO 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 50 MHz. The Des on the other hand shows no error when the noise frequency is less than 50 MHz.
