Crosspoint Switches ensure low noise and low jitter.

Press Release Summary:




Models SN65LVCP22 and SN65LVP23 are 2 x 2 crosspoint switches that provide 2:2 buffering, 1:2 splitting, and 2:1 multiplexing. Model SN65LVCP22 supports LVPECL/CML to LVDS level translations, while Model SN65LVCP23 supports LVDS/CML to LVPECL level translations. Both feature 50 ps peak-to-peak jitter, 1.7 ns switch time, and operating temperature of -40 to +85°C. They meet redundant serial bus transmission needs of fault-tolerant systems.

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



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 a fully differential data path 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
o Low-Jitter, High Speed (>1000 Mbps)
o 50ps of Peak-to-Peak Jitter with PRBS = 223-1 Pattern
o <200 mW (typical), 300mW (maximum) Total Power Dissipation
o 1.7 ns Fast Switch Time
o 0.65 ns Fast Propagation Delay
o -40oC to 85oC Operating Temperature
o Inter-Operates with TIA/EIA-644-A LVDS Standard

Additional Features of the SN65LVCP23
o 50ps of Peak-to-Peak Jitter with PRBS = 223-1 Pattern
o 1.7 ns Fast Switch Time
o 0.75 ns Fast Propagation Delay
o -40oC to 85oC Operating Temperature
