DESCRIPTION
This family of four LVDS data line receivers offers the
widest common-mode input voltage range in the
industry. These receivers provide an input voltage
range specification compatible with a 5-V PECL
signal as well as an overall increased ground-noise
tolerance. They are in industry standard footprints
with integrated termination as an option.
Precise control of the differential input voltage
thresholds allows for inclusion of 50 mV of input
voltage hysteresis to improve noise rejection on
slowly changing input signals. The input thresholds
are still no more than ±50 mV over the full input
common-mode voltage range.
The high-speed switching of LVDS signals usually
necessitates the use of a line impedance matching
resistor at the receiving-end of the cable or transmission media. The SN65LVDT series of
receivers eliminates this external resistor by
integrating it with the receiver. The nonterminated
SN65LVDS series is also available for multidrop or
other termination circuits.
