General Description
The MAX9130 is a single low-voltage differential signal-
ing (LVDS) line receiver ideal for applications requiring
high data rates, low power, and low noise. The device
is guaranteed to receive data at speeds up to 500Mbps
(250MHz).
The MAX9130 accepts an LVDS differential input and
translates it to an LVTTL/LVCMOS output. The fail-safe
feature sets the output high when the inputs are undriv-
en and open, terminated, or shorted. The device sup-
ports a wide common-mode input range, allowing a
ground potential difference and common-mode noise
between the driver and the receiver. The MAX9130
conforms to the ANSI/TIA/EIA-644 LVDS standard.
The MAX9130 operates from a single +3.3V supply,
and is specified for operation from -40C to +85C. It is
available in a space-saving 6-pin SC70 package. Refer
to the MAX9110/MAX9112 data sheet for single/dual
LVDS line drivers. Refer to the MAX9115 for a lower
speed (200Mbps) single LVDS line receiver in SC70.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
