The MAX9171/MAX9172 feature LVDS inputs for inter-
facing high-speed digital circuitry. The LVDS interface
standard is a signaling method intended for point-to-
point communication over controlled-impedance
media, as defined by the ANSI TIA/EIA-644 standards.
The technology uses low-voltage signals to achieve fast
transition times and minimize power dissipation and
noise immunity. The MAX9171/MAX9172 convert LVDS
Single/Dual LVDS Line Receivers with
“In-Path” Fail-Safe

signals to LVCMOS/LVTTL signals at rates in excess of
500Mbps. These devices are capable of detecting dif-
ferential signals as low as 100mV and as high as 1.2V
within a 0 to V
input-output function table.
The MAX9171/MAX9172 fail-safe drives the receiver
output high when the differential input is:
• Open
• Undriven and shorted
• Undriven and terminated
Without fail-safe, differential noise at the input may
switch the receiver and appear as data to the receiving
system. An open input occurs when a cable and termi-
nation are disconnected. An undriven, terminated input
occurs when a cable is disconnected with the termina-
tion still connected across the receiver inputs or when
the driver of a receiver is in high impedance. An undriv-
en, shorted input can occur due to a shorted cable.
