A sinusoidal signal is AC coupled to the VDD33 and VDDIOsupplies 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 50MHz. The Des on the other hand shows no error when the noise frequency is less than 50 MHz. DC Electrical Characteristics Over recommended operating supply and temperature ranges unless otherwise specified. (1) (2) (3) Symb Parameter Conditions Pin/Freq.

Typical specifications are estimations only and are not ensured. (2) Typical values represent most likely parametric norms at VDD = 3.3V, Ta = +25 degC, and at the Recommended Operation Conditions at the time of product characterization and are not ensured. (3) Current into device pins is defined as positive. Current out of a device pin is defined as negative. Voltages are referenced to ground except VOD and ΔVOD, which are differential voltages.
