1.5 Gbps 2X2 LVDS Crosspoint Switch from the PowerWise® Family
National Semiconductor
Description
The DS10CP152 is a 1.5 Gbps 2x2 LVDS crosspoint switch optimized for high-speed signal routing and switching over lossy FR-4 printed circuit board backplanes and balanced cables. Fully differential signal paths ensure exceptional signal integrity and noise immunity. The non-blocking architecture allows connections of any input to any output or outputs. Wide input common mode range allows the switch to accept signals with LVDS, CML and LVPECL levels; the output levels are LVDS. A very small package footprint requires a minimal space on the board while the flow-through pinout allows easy board layout. Each differential input and output is internally terminated with a 100Ω resistor to lower device return losses, reduce component count and further minimize board space.
Features
• DC - 1.5 Gbps low jitter, low skew, low power operation
• Pin configurable, fully differential, non-blocking architecture
• Wide Input Common Mode Voltage Range allows DC-coupled interface to LVDS, CML and LVPECL drivers
• On-chip 100Ω input and output termination minimizes insertion and return losses, reduces component count and minimizes board space
• 7 kV ESD on LVDS I/O pins protects adjoining components
• Small SOIC-16 space saving package
