Description

Dual low voltage differential signaling (LVDS),

driver receiver designed, packaged and qualified

for use in aerospace environments in a low-power

and fast-transmission standard, and operating at

3.3 V power supply (3.6 V max operating and

4.8 V AMR). The RHFLVDSR2D2 operates over a

controlled impedance of 100-ohm transmission

media that may be printed circuit board traces,

back planes, or cables.

The circuit features an internal fail-safe function to

ensure a known state in case of an input short

circuit or floating input. All pins have cold spare

buffers to ensure they are in high impedance

The RHFLVDSR2D2 can operate over a large

temperature range of -55 °C to +125 °C and it is

housed in an hermetic Ceramic Flat-18 package.
