Stress in excess of any of the individual Absolute Maximum Ratings can cause immediate catastrophic damage to the
Active Cable even if all other parameters are within Recommended Operation Conditions. It should not be assumed
that limiting values of more than one parameter can be applied to the Active Cable concurrently. Exposure to any of the
Absolute Maximum Ratings for extended periods can adversely affect reliability.

1. The position for case temperature measurement is shown in Figure 4.
2. This is the maximum voltage that can be applied across the differential inputs without damaging the input circuitry. The equivalent input
differential peak-to-peak voltage is twice this number.
Recommended Operating Conditions
Recommended Operating Conditions specify parameters for which the electrical characteristics hold unless otherwise
noted. Electrical characteristics are not defined for operation outside the Recommended Operating Conditions, reliability
is not implied and damage to the Active Cable may occur for such operation over an extended period of time.

3. Power Supply Noise is defined as the peak-to-peak noise amplitude over the frequency range at the host supply side of the recommended
power supply filter with the Active Cable-end and recommended filter in place. Voltage levels including peak-to-peak noise are limited to the
recommended operating range of the associated power supply. See Figure 5 for a recommended power supply filter.

to the time when the cable enables TWS access. The cable at that point is fully functional.
