(1) V_DDIO < V_DD33 + 0.3 V
(2) Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC coupled to the V_DD33 and V_DDIOsupplies
with amplitude = 100 mVp-p measured at the device V_DD33 and V_DDIO 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.
