DS90CP04
1.5 Gbps 4x4 LVDS Crosspoint Switch
General Description
DS90CP04 is a 4x4 digital cross-point switch with broadside
input and output pins for efficient board layout. It utilizes Low
Voltage Differential Swing (LVDS) technology for low power,
high-speed operation. Data paths are fully differential from
input to output for low noise. The non-blocking architecture
allows connections of any input to any output or outputs. The
switch matrix consists of four differential 4:1 multiplexes.
Each output channel connects to one of the four inputs com-
mon to all multiplexers.
A simple serial control interface or a configuration select port
is activated by the state of the MODE pin. When utilizing the
serial control interface a single load command will update the
new switch configuration for all outputs simultaneously.
