Description
The RHFLVDS228A 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 RHFLVDS228A 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 V_CC is tied to GND. The
RHFLVDS228A can operate over a wide
temperature range of -55 °C to +125 °C and it is
housed in an hermetic Ceramic Flat-64 package.
