Quad LVDS Line Driver with

Flow-Through Pinout

General Description

Features

The MAX9123 quad low-voltage differential signaling

(LVDS) differential line driver is ideal for applications

requiring high data rates, low power, and low noise. The

MAX9123 is guaranteed to transmit data at speeds up to

800Mbps (400MHz) over controlled impedance media of

approximately 100Ω. The transmission media may be

printed circuit (PC) board traces, backplanes, or cables.

ꢀ Flow-Through Pinout

Simplifies PC Board Layout

Reduces Crosstalk

ꢀ Pin Compatible with DS90LV047A

ꢀ Guaranteed 800Mbps Data Rate

ꢀ 250ps Maximum Pulse Skew

The MAX9123 accepts four LVTTL/LVCMOS input levels

and translates them to LVDS output signals. Moreover,

the MAX9123 is capable of setting all four outputs to a

high-impedance state through two enable inputs, EN and

EN, thus dropping the device to an ultra-low-power state

of 16mW (typ) during high impedance. The enables are

common to all four transmitters. Outputs conform to the

ANSI TIA/EIA-644 LVDS standard. Flow-through pinout

simplifies PC board layout and reduces crosstalk by sep-

arating the LVTTL/LVCMOS inputs and LVDS outputs.
