Quad LVDS Line Receivers with

Integrated Termination

General Description

Features

The MAX9125/MAX9126 quad low-voltage differential

signaling (LVDS) line receivers are ideal for applica-

tions requiring high data rates, low power, and reduced

noise. The MAX9125/MAX9126 are guaranteed to

receive data at speeds up to 500Mbps (250MHz) over

controlled-impedance media of approximately 100Ω.

The transmission media may be printed circuit (PC)

board traces or cables.

ꢀ Integrated Termination Eliminates Four External

Resistors (MAX9126)

ꢀ Pin Compatible with DS90LV032A

ꢀ Guaranteed 500Mbps Data Rate

ꢀ 300ps Pulse Skew (max)

ꢀ Conform to ANSI TIA/EIA-644 LVDS Standard

ꢀ Single +3.3V Supply

The MAX9125/MAX9126 accept four LVDS differential

inputs and translate them to 3.3V CMOS outputs. The

MAX9126 features integrated parallel termination resis-

tors (nominally 115Ω), which eliminate the requirement

for four discrete termination resistors and reduce stub

length. The MAX9125 inputs are high impedance and

require an external termination resistor when used in a

point-to-point connection.

The devices support a wide common-mode input range

of 0.05V to 2.35V, allowing for ground potential differ-

ences and common-mode noise between the driver

and the receiver. A fail-safe feature sets the output high

when the inputs are open, or when the inputs are

undriven and shorted or parallel terminated. The EN

and EN inputs control the high-impedance output and

are common to all four receivers. Inputs conform to the

ANSI TIA/EIA-644 LVDS standard. The MAX9125/

MAX9126 operate from a single +3.3V supply, are

specified for operation from -40°C to +85°C, and are

available in 16-pin TSSOP and SO packages. Refer to

the MAX9124 data sheet for a quad LVDS line driver.
