Description
Max9155 Low-jitter, Low-noise Lvds Repeater In An Sc70 Package
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX9155 is a low-voltage differential signaling
(LVDS) repeater, which accepts a single LVDS input
and duplicates the signal at a single LVDS output. Its
low-jitter, low-noise performance makes it ideal for
buffering LVDS signals sent over long distances or
noisy environments, such as cables and backplanes.
The MAX9155’s tiny size makes it especially suitable for
minimizing stub lengths in multidrop backplane appli-
cations. The SC70 package (half the size of a SOT23)
allows the MAX9155 to be placed close to the connec-
tor, thereby minimizing stub lengths and reflections on
the bus. The point-to-point connection between the
MAX9155 output and the destination IC, such as an
FPGA or ASIC, allows the destination IC to be located
at greater distances from the bus connector.

nication in high-speed links that are highly sensitive to
timing errors, especially those incorporating clock-and-
data recovery, PLLs, serializers, or deserializers. The
MAX9155’s switching performance guarantees a
200Mbps data rate, but minimizes radiated noise by
guaranteeing 0.5ns minimum output transition time.
The MAX9155 has fail-safe circuitry that sets the output
high for undriven open, short, or terminated inputs.
The MAX9155 operates from a single +3.3V supply and
consumes only 10mA over a -40°C to +85°C tempera-
ture range. Refer to the MAX9129 data sheet for a quad
bus LVDS driver, and to the MAX9156 data sheet for a
low-jitter, low-noise LVPECL-to-LVDS level translator in
an SC70 package.
