LT1675/LT1675-1

250MHz, Triple and Single

RGB Multiplexer with Amplifiers

configured for a fixed gain of 2, eliminating six external

gain setting resistors. The SPDT switches are designed to

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

pling to the input.

FEATURES

■

100MHz Pixel Switching

■

–3dB Bandwidth: 250MHz

■

Channel Switching Time: 2.5ns

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.

■

Expandable to Larger Arrays

■

Drives Cables Directly

■

High Slew Rate: 1100V/µs

■

Low Switching Transient: 50mV

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

of 250MHz. Power supply requirements are ±4V to ±6V

and power dissipation is only 300mW on ±5V, 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.

■

Shutdown Supply Current: 100µA

■

Output Short-Circuit Protected

■

^{Available in Sma}U^{ll 16-Pin SSOP Package}

APPLICATIO S

■

RGB Switching

■

Workstation Graphics

■

Pixel Switching

■

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.

DESCRIPTIO

The LT^®1675 is a high speed RGB multiplexer designed

for 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
