All voltages are relative to their respective ground.
The supply current values for all four channels are combined when running at identical data rates. Output supply current values are specified with no output load present. The
The minimum pulse width is the shortest pulse width at which the specified pulse-width distortion is guaranteed.
The maximum data rate is the fastest data rate at which the specified pulse-width distortion is guaranteed.

Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 8 through Figure 10 for information on per-
channel supply current for unloaded and loaded conditions. See the Power Consumption section on Page 20 for guidance on calculating the per-channel supply current for a
given data rate.
supply current associated with an individual channel operating at a given data rate may be calculated as described in the Power Consumption section on Page 20. See Figure 8
through Figure 10 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 11 through Figure 14 for total I
