LT1675/LT1675-1

250MHz, Triple and Single

RGB Multiplexer with Current Feedback Amplifiers

configured for a fixed gain of 2, eliminating six external

FEATURES

gain setting resistors. The SPDT switches are designed to

be break-before-make to minimize unwanted signals cou-

pling to the input.

■

100MHz Pixel Switching

–3dB Bandwidth: 250MHz

Small 16-Pin SSOP Package

Channel Switching Time: 2.5ns

Expandable to Larger Arrays

Drives Cables Directly

High Slew Rate: 1100V/µs

Low Switching Transient: 50mV

Shutdown Supply Current: 0mA

Output Short-Circuit Protected

The LT1675-1 is a single version with two inputs, a single

output and is ideal for a single channel application such as

video sync.

The key to the LT1675 fast switching speed is Linear

Technology’sproprietaryhighspeedbipolarprocess.This

MUX can toggle between sources in excess of 100MHz,

has a slew rate over 1000V/µs and has a –3dB bandwidth

of250MHz. ThespeedandeaseofuseoftheLT1675make

it ideal for high performance PCs, workstations and pro-

fessional video monitors. The input-referred switching

transient is only 50mV_P-Pand lasts just 5ns, making it

virtually undetectable. Power supply requirements are

or 100mW for the LT1675-1. The expandable feature uses

the disable pin to reduce the power dissipation to near

0mW in the off parts.

DESCRIPTION

Unlike competitive solutions that are in bulky high pin

count packages, the LT1675 is in a 16-lead narrow body

SSOP. This small footprint, the size of an SO-8, results in

a very clean high performance solution. The LT1675-1 is

available in the tiny MSOP and the SO-8.

TheLT^®1675isahighspeedRGBmultiplexerdesignedfor

pixel switching and fast workstation graphics.

Included on chip are three SPDT switches and three

current feedback amplifiers. The current feedback ampli-

fiers drive double-terminated 50Ω or 75Ω cables and are
