LVDS Mux/Repeater  
Description  
Features  
• Meets or Exceeds the Requirements of ANSI TIA/  
The PI90LV022 and PI90LVB022 are differential line drivers and  
receivers that use Low Voltage Differential Signaling (LVDS) to  
achieve signaling rates as high as 650 Mbps. The receiver outputs  
can be switched to either or both drivers through the multiplexer  
control signals S0 and S1. This allows the flexibility to perform  
splitter or signal routing functions with a single device.  
EIA-644-1995  
• Designed for Signaling Rates up to 650 Mbit/s (325 MHz)

• Accepts±350mVdifferentialinputs  
• Wide common mode input voltage range: 0.2V to 2.7V  
• Output drivers are high impedance when disabled or

• Inputs are open, short, and terminated fail safe  
• PropagationDelayTime:3.5ns  
• ESD protection is 10kV on bus pins  
The intended application of these devices and signaling technique  
is for both point-to-point base-band (PI90LV022) and multipoint
