LT1675/LT1675-1
250MHz, Triple and Single
RGB Multiplexer with Current Feedback 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.
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’s proprietary high speed bipolar process. This
MUX can toggle between sources in excess of 100MHz,
has a slew rate over 1000V/
μ
s and has a –3dB bandwidth
of 250MHz. The speed and ease of use of the LT1675 make
it ideal for high performance PCs, workstations and pro-
fessional video monitors. The input-referred switching
transient is only 50mV
P-P
and lasts just 5ns, making it
virtually undetectable. 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.
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.
