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.
