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 levels 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, disabling 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.
