LVDS Dual High Speed Differential Driver
National Semiconductor
Description
The DS90LV027A is a dual LVDS driver device optimized for high data rate and low power applications. The device is designed to support data rates in excess of 600Mbps (300MHz) utilizing Low Voltage Differential Signaling (LVDS) technology. The DS90LV027A 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 DS90LV027A has a flow-through design for easy PCB layout. The differential driver outputs provides low EMI with its typical low output swing of 360 mV. It is perfect for high speed transfer of clock and data. The DS90LV027A can be paired with its companion dual line receiver, the DS90LV028A, or with any of National"s LVDS receivers, to provide a high-speed point-to-point LVDS interface.
