3 Description

The DS90LV049H is a dual CMOS 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 TSSOP package

allows for flow-through routing for easy PCB layout.

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 fail-safe 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.
