(1) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except: VTH, VTL, VOD and ΔVOD.
(2) All typical values are given for: VDD = +3.3 V, TA = +25°C.
(3) The DS90LV049H'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.
(4) Output short circuit current (IOS) is specified as magnitude only, minus sign indicates direction only.
(5) 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.
