Description

PI90LV03 and PI90LVB03 are single LVDS Repeaters that use

low-voltage differential signaling (LVDS) to support data rates up

to 660 Mbps. The PI90LVB03 features high-drive output. Both

products are designed for applications requiring high-speed, low-

power consumption, low-noise generation, and a small package.

The LVDS Repeaters take an LVDS input signal and provide an

LVDS output to address various interface logic requirements such

as signal isolation, repeater, stub length, and Optical Transceiver

Modules. In many large systems, signals are distributed across

backplanes, and the distance between the transmission line and the

unterminated receivers are one of the limiting factors for system

speed. The buffers can be used to reduce the ‘stub length’ by stra-

tegic device placement along the trace length. They can improve

system performance by allowing the receiver to be placed very

close to the main transmission line or very close to the connector

on the card. Longer traces to the LVDS receiver can then be placed

after the buffer.

The buffer’s wide input dynamic range enables them to receive dif-

ferential signals from LVPECL and LVDS sources. The devices can

be used as compact high-speed serial translators between LVPECL

and LVDS data lines. The differential translation provides a simple

way to mix and match Optical Transceiver ICs from various vendors

without redesigning the interfaces.

Applications

The PI90LV03 and PI90LVB03 provide differential translation

between LVDS and PECL devices for high-speed, point-to-point

interface and telecom applications:
