LVDS Single High Speed Differential Driver
DS90LV017A LVDS Single High Speed Differential Driver
March 2000
General Description
The DS90LV017A is a single LVDS driver device optimized
for high data rate and low power applications. The
DS90LV017Ais a current mode driver allowing power dissipation to remain low even at high frequency. In addition, the
short circuit fault current is also minimized. The device is designed to support data rates in excess of 600Mbps
(300MHz) utilizing Low Voltage Differential Signaling (LVDS)
technology.
The device is in a 8-lead small outline package. The
DS90LV017A has a flow-through design for easy PCB layout. The differential driver outputs provides low EMI with its
typical low output swing of 355 mV.TheDS90LV017A can be
paired with its companion single line receiver, the
DS90LV018A, or with any of National’s LVDS receivers, to
provide a high-speed point-to-point LVDS interface.

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
Note 3: All typicals are given for: V
Note 4: These parameters are guaranteedby design. The limits are based on statistical analysis of the device performance over PVT (process, voltage, temperature)
ranges.
