General Description

The MAX9115 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 200Mbps

(100MHz).

The MAX9115 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 MAX9115

conforms to the ANSI TIA/EIA-644 LVDS standard.

The MAX9115 operates from a single +3.3V supply,

and is specified for operation from -40°C to +85°C. It is

available in a space-saving 5-pin SC70 package. Refer

to the MAX9110/MAX9112 data sheet for single/dual

LVDS line drivers.
