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. The MAX4548/MAX4549 feature 35Ω max on-resistance, 7Ω on-resistance matching between channels, 5Ω on-resistance flatness, and 0.07% total harmonic distortion (THD). Additionally, they feature off-isolation of -85dB at 20kHz and -72dB at 10MHz, with crosstalk of -85dB at 20kHz and -55dB at 10MHz. The MAX4548 uses a 2-wire I²-compatible serial interface, while the MAX4549 uses a 3-wire SPI™/QSPI™/MICROWIRE™-compatible serial interface. These parts are available in 36-pin SSOP packages and are specified for the extended (-40°C to +85°C) operating range.
