Description

The RHFLVDS2281 is an 8-channel, 4x4

crosspoint switch base, on low voltage differential

signaling (LVDS) for low-power and high-speed

communications. The two 4x4 multiplexers allow

connection from any of the four inputs to any of

the four outputs.

Packaged and qualified for use in aerospace

environments in a low-power, fast-transmission

standard, the RHFLVDS2281 operates at 3.3 V

power supply (3.6 V max. operating and 4.8 V

AMR) and a common mode of -4 V to +5 V. The

LVDS outputs operate 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 a floating input.

All pins have cold spare buffers to ensure they are

in high impedance when VCC is tied to GND. The

RHFLVDS2281 can operate over a wide

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

housed in an hermetic Ceramic Flat-64 package.
