DS90LV049 LVDS Dual Line Driver with Dual Line Receiver
General DescriptionThe DS90LV049isa dual CMOS flow-through differential
line driver-receiver pair designedfor applications requiring
ultra low power dissipation, exceptional noise immunity, and
high data throughput.The deviceis designedto support data
ratesin excessof 400 Mbps utilizing Low Voltage Differential
Signaling (LVDS) technology.
The DS90LV049 drivers accept LVTTL/LVCMOS signals and
translate themto LVDS signals. On the other hand, the
receivers accept LVDS signals and translate themto3V
CMOS signals. The LVDS input buffers have internal failsafe
biasing that placesthe outputstoa knownH (high) statefor
floating receiver inputs.In addition,the DS90LV049 supports TRI-STATE functionfora low idle power state when the
deviceisnotin use.
The EN andEN inputs are ANDed together and control the
TRI-STATE outputs. The enables are commontoall four
gates.
