Product overview

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.
