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 sup-  
plies 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 fe a ture 35ma x on-re sis-  
tance, 7on-resistance matching between channels,  
5on-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 I2C-compatible serial interface, while  
the MAX4549 uses a 3-wire SPI™/QSPI™/MICROWIRE™-  
compatible serial interface. These parts are available in  
36-p in SSOP p a c ka g e s a nd a re s p e c ifie d for the
