DS90LV017A LVDS Single High Speed Differential Driver
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.

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

same channel. Note 9: t
SKD3
, Differential Part to Part Skew, is defined as the difference between the minimum and maximum specified differential propagation delays. This speci-
fication applies to devices at the same V

and within 5˚C of each other within the operating temperature range.
Note 10: t
SKD4
, part to part skew, is the differential channel to channel skew of any event between devices. This specification applies to devices over recommended
operating temperature and voltage ranges, and across process distribution. t
