DESCRIPTION

The DS90LV001 LVDS-LVDS Buffer takes an LVDS

input signal and provides an LVDS output signal. In

many large systems, signals are distributed across

backplanes, and one of the limiting factors for system

speed is the stub length or the distance between

the transmission line and the unterminated receivers on individual cards. Although it is generally

recognized that this distance should be as short as

possible to maximize system performance, real-world

packaging concerns often make it difficult to make the

stubs as short as the designer would like.

The DS90LV001, available in the WSON package,

will allow the receiver to be placed very close to the

main transmission line, thus improving system

performance.

A wide input dynamic range will allow the

DS90LV001 to receive differential signals from

LVPECL as well as LVDS sources. This will allow the

device to also fill the role of an LVPECL-LVDS

translator.

An output enable pin is provided, which allows the

user to place the LVDS output in TRI-STATE.

The DS90LV001 is offered in two package options,

an 8 pin WSON and SOIC.
