DESCRIPTION
The DS90LV049Q 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 DS90LV049Q 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 DS90LV049Q 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.
