Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
Note 2: Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except: V
V
Note 3: Both, driver and receiver inputs are static. All LVDS outputs have 100 Ω load. All LVCMOS outputs are floating. None of the outputs have any lumped
capacitive load.
Note 4: All typical values are given for: V
Note 5: These parameters are guaranteed by design. The limits are based on statistical analysis of the device performance over PVT (process, voltage,
temperature) ranges.
Note 6: The DS90LV049’s drivers are current mode devices and only function within datasheet specifications when a resistive load is applied to their outputs. The
typical range of the resistor values is 90 Ω to 110 Ω.
Note 7: t
