... The MAX9171 is a single LVDS receiver and the MAX9172 is a dual LVDS receiver. Both devices con- form to the ANSI TIA/EIA-644 LVDS standard and con- vert LVDS to LVTTL/LVCMOS-compatible outputs. A fail-safe feature sets the outputs high when the inputs are undriven and open, terminated, or shorted ...

... IN1- — onl y) EP Detailed Description 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 ...

... OUT_ Figure 3. Propagation Delay and Transition Time Waveforms _______________________________________________________________________________________ The MAX9171/MAX9172 have in-path fail-safe that is compatible with in-path fail-safe receivers, such as the DS90LV018A and DS90LV028A. Refer to the MAX9111/ MAX9113 data sheet for pin-compatible receivers with parallel fail-safe and lower jitter. Refer to the MAX9130 data sheet for a single LVDS receiver with parallel fail- safe in an SC70 package ...

... When using the MAX9171/MAX9172, minimize the dis- tance between the input termination resistors and the MAX9171/MAX9172 receiver inputs. Use a single 1% surface-mount resistor. For LVDS applications, a four-layer PCB that provides separate power, ground, LVDS signals, and output sig- nals is recommended ...
