Data paths are fully differential from input to output for low noise generation and low pulse width distortion. The non-blocking design allows connection of any input to any output or outputs. LVDS I/O enable high speed data transmission for point-to-point interconnects. This device can be used as a high speed differential crosspoint, 2:1 mux, 1:2 demux, repeater or 1:2 signal splitter. The mux and demux functions are useful for switching between primary and backup circuits in fault tolerant systems. The 1:2 signal splitter and 2:1 mux functions are useful for distribution of serial bus across several rack-mounted backplanes. The DS90CP22 accepts LVDS signal levels, LVPECL levels directly or PECL with attenuation networks. The individual LVDS outputs can be put into TRI-STATE by use of the enable pins.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
