DS90LV049H
High Temperature 3V LVDS Dual Line Driver and
Receiver Pair
General Description
The DS90LV049H 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 DS90LV049H drivers accept LVTTL/LVCMOS signals
and translate them to LVDS signals. 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 DS90LV049H 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.
