DS90LV011AH
High Temperature 3V LVDS Differential Driver
General Description
The DS90LV011AH is an LVDS driver optimized for high
data rate and low power applications. The DS90LV011AH 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 designed to support
data rates in excess of 400Mbps (200MHz) utilizing Low
Voltage Differential Signaling (LVDS) technology.
The device is offered in a 5-lead small outline transistor
package. The LVDS outputs have been arranged for easy
PCB layout. The differential driver outputs provide low EMI
with its typical low output swing of 350 mV. The
DS90LV011AH can be paired with its companion single line
receiver, the DS90LT012AH, or with any of National's LVDS
receivers, to provide a high-speed LVDS interface.
