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.
