RHFLVDS228A

Rad-hard, dual 4x4 crosspoint switch LVDS

Datasheet - production data

• Large input common mode: -4 V to +5 V

• Guaranteed up to 300 krad TID

• SEL immune up to 135 MeV.cm²/mg

• SET/SEU immune up to 22 MeV.cm²/mg

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.

Ceramic Flat-64

The upper metallic lid is

electrically connected to ground.

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.

Features

• LVDS input/output

• Multiple configuration: Mux, repeater and

splitter

• ANSI TIA/EIA-644 compliant

• 400 Mbps LVDS (200 MHz)

• 200 MHz clock channel

• Cold spare on all pins

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

• Fail-safe function

in high impedance when V is tied to GND. The

• 3.3 V operating power supply

• 4.8 V absolute rating

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.

• Hermetic package

• Power consumption: 220 mW at 3.3 V
