DS90LV017 LVDS Single High Speed Differential Driver
August 2005
DS90LV017
LVDS Single High Speed Differential Driver
General Description
The DS90LV017 is a single LVDS driver device optimized for
high data rate and low power applications. The DS90LV017
is 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 in a 8-lead small
Outline Package. The DS90LV017 has a flow-through de-
sign for easy PCB layout. The differential driver outputs
provides low EMI with its low output swings typically 340 mV.

DIFFERENTIAL DRIVER CHARACTERISTICS
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
OD
.
Note 3:
All typicals are given for: V
CC
= +3.3V and T
A
= +25˚C.
Note 4:
ESD Rating: HBM (1.5 kΩ, 100 pF)
≥

includes probe and fixture capacitance.
Note 6:
