Fault-Tolerant Systems Benefit from TI Crosspoint Switches

9/18/2003 - Designers of fault-tolerant systems can significantly reduce noise and jitter with the introduction of two new 2x2 crosspoint switches from Texas Instruments Incorporated (TI) [NYSE: TXN]. The switches provide high-speed operation and use fully differential data paths to ensure low-noise generation, fast switching times, low pulse width distortion and low jitter. A single device is provided to support the redundant serial bus transmission needs of fault-tolerant systems found in applications such as optical networking, wireless infrastructure and data communications systems.

The SN65LVCP22 and SN65LVP23 2x2 crosspoint switches support 2:2 buffering (repeating), 1:2 splitting, 2:1 multiplexing and 2x2 switching. In addition, the devices incorporate wide common-mode (OV to 4V) receivers, allowing for the receipt of LVDS, LVPECL and CML signals. The SN65LVCP22 supports LVPECL/CML to LVDS level translations and the SN65LVCP23 supports LVDS/CML to LVPECL level translations. To establish accurate alignment of outputs in all applications, the output channel-to-channel skew is less than 10ps (typical) and 50ps (maximum).
