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 common 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.
