DS90LV047A
3V LVDS Quad CMOS Differential Line Driver
General Description
The DS90LV047A is a quad CMOS flow-through differential
line driver designed for applications requiring ultra low power
dissipation and high data rates. The device is designed to
support data rates in excess of 400 Mbps (200 MHz) utilizing
Low Voltage Differential Signaling (LVDS) technology.
The DS90LV047A accepts low voltage TTL/CMOS input lev-
els and translates them to low voltage (350 mV) differential
output signals. In addition, the driver supports a TRI-STATE®
function that may be used to disable the output stage, dis-
abling the load current, and thus dropping the device to an
ultra low idle power state of 13 mW typical. The
DS90LV047A has a flow-through pinout for easy PCB layout.
The EN and EN* inputs are ANDed together and control the
TRI-STATE outputs. The enables are common to all four
drivers. The DS90LV047A and companion line receiver
(DS90LV048A) provide a new alternative to high power
psuedo-ECL devices for high speed point-to-point interface
applications.
