Description : Quad 2x2 400 Mbps Crosspoint Switch

INTRODUCTION

The UT54LVDM228 is a Quad 2x2 Crosspoint Switch utilizing Low Voltage Differential Signaling (LVDS) technology for low power, high speed operation. 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 on each Switch. LVDS I/O enable high speed data transmission for point-to point or multidrop 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 a bus across several rack-mounted backplanes.

Description : LVDS Dual 2x2 Crosspoint/Repeater Switch

Description
The PI90LV044 and PI90LVB044 are monolithic dual 2x2 asynchronous Crosspoint/repeater Switches. The Crosspoint function is based on a multiplexer tree architecture. Each 2x2 Switch can be considered as a pair of 2:1 multiplexers that share the same inputs. The signal path through each Switch is fully differential with minimal propagation delay. The signal path is unregistered, so no clock is required for the data inputs. The signal line drivers and receivers use Low Voltage Differential Signaling (LVDS) to achieve signaling rates as high as 650Mbps.

    - 100Ω load (PI90LV044)
    - 50Ω load Bus LVDS Signaling (PI90LVB044)
• Accepts ±350mV differential inputs
• Wide common mode input range: 0.2V to 2.7V
• Output drivers are high impedance when disabled or when VCC ≤ 1.5V
• Inputs are open, short, and terminated fail safe
• Propagation Delay Time: 3.5ns
