... LVDS signals and translate them CMOS signals. The LVDS input buffers have internal failsafe biasing that places the outputs to a known H (high) state for floating receiver inputs. In addition, the DS90LV049H supports a TRI-STATE function for a low idle power state when the device is not in use. ...

... 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 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. ...

... The TRI-STATE function allows the device outputs to be disabled, thus obtaining an even lower power state when the transmission of data is not required. The DS90LV049H has a flow-through pinout that allows for easy PCB layout. The LVDS signals on one side of the device easily allows for matching electrical lengths of the ...
