Serially Controlled, Triple 3x2 Audio/Video Crosspoint Switches
General Description
The MAX4548/MAX4549 serial-interface, programmable, triple 3x2 audio/video crosspoint switches are ideal for multimedia applications.
The devices include three crosspoint switch matrices, each containing three inputs and two outputs.
To improve off-isolation, each switch matrix has a shunt input and each output is selectively programmable for clickless or regular-mode operation.
A selectable set of internal resistive
voltage dividers supplies DC bias for each output when using AC-coupled inputs.
To improve crosstalk, the
voltage dividers include four externally accessible bypass points.
