DS90LV049 3V LVDS Dual Line Driver with Dual Line Receiver
March 2003
DS90LV049
3V LVDS Dual Line Driver with Dual Line Receiver
General Description
The DS90LV049 is a dual CMOS flow-through differential
line driver-receiver pair designed for applications requiring
ultra low power dissipation, exceptional noise immunity, and
high data throughput. The device is designed to support data
rates in excess of 400 Mbps utilizing Low Voltage Differential
Signaling (LVDS) technology.
The DS90LV049 drivers accept LVTTL/LVCMOS signals and
translate them to LVDS signals. On the other hand, the
receivers accept LVDS signals and translate them to 3 V
CMOS signals. The LVDS input buffers have internal failsafe
biasing that places the outputs to a known H (high) state for
floating receiver inputs. In addition, the DS90LV049 supports
a TRI-STATE function for a low idle power state when the
device is not in use.
The EN and EN inputs are ANDed together and control the
TRI-STATE outputs. The enables are common to all four
gates.
