TI Crosspoint Switches Ensure Low-Noise, Low Jitter in Fault-Tolerant Systems

Sep 17, 2003

DALLAS (September 17, 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]. Announced today, 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. (See www.ti.com/sc03197.)


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).

Additional Features of the SN65LVCP22

  • Low-Jitter, High Speed (>1000 Mbps) 
  • 50ps of Peak-to-Peak Jitter with PRBS = 2(23)-1 Pattern 
  • <200 mW (typical), 300mW (maximum) Total Power Dissipation 
  • 1.7 ns Fast Switch Time 
  • 0.65 ns Fast Propagation Delay 
  • -40oC to 85oC Operating Temperature 
  • Inter-Operates with TIA/EIA-644-A LVDS Standard

Additional Features of the SN65LVCP23

  • 50ps of Peak-to-Peak Jitter with PRBS = 2(23)-1 Pattern 
  • 1.7 ns Fast Switch Time 
  • 0.75 ns Fast Propagation Delay 
  • -40oC to 85oC Operating Temperature

Availability, Packaging and Pricing

The SN65LVCP22 and SN65LVCP23 are available now from TI and its authorized worldwide distributors in 16 lead SOIC and TSSOP packages. Suggested resale pricing in 1,000 piece quantities is $3.89 for the SN65LVCP22 and $4.95 for the SN65LVCP23.
