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.
