19-1496; Rev 0; 6/99 MAX4548/MAX4549 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.
