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.
