Description
Max9180 400mbps, Low-jitter, Low-noise Lvds Repeater In An Sc70 Package
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX9180 is a 400Mbps, 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 dis-
tances or noisy environments, such as cables and
backplanes.
The MAX9180’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 MAX9180 to be placed close to the connec-
tor, thereby minimizing stub lengths and reflections on
the bus. The point-to-point connection between the
MAX9180 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
MAX9180’s switching performance guarantees a
400Mbps data rate, but minimizes radiated noise by
guaranteeing 0.5ns minimum output transition time.
The MAX9180 has fail-safe circuitry that sets the output
high for undriven open, short, or terminated inputs.
The MAX9180 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 (BLVDS) driver, and to the MAX9181 data
sheet for a low-jitter, low-noise 400Mbps LVPECL-to-
LVDS level translator in an SC70 package.
