Detailed Description
The MAX4548/MAX4549 are serial-interface, program-
mable, triple 3x2 audio/video crosspoint switches. Each
device contains two crosspoint switches with a com-
mon bypass network and another crosspoint switch
with its own bypass network. The switches are indepen-
dently controlled through the on-chip serial interface.
The MAX4548 uses a 2-wire I2C-compatible serial com-
munications protocol, while the MAX4549 uses a 3-wire
SPI/QSPI/MICROWIRE-compatible serial communica-
tions protocol.
These ICs include twelve selectable bias-resistor net-
works (one for each input) for use with AC-coupled
input signals. They operate from a single supply of
+2.7V to +5.5V and are optimized for use in the audio
frequency range to 20kHz and at video frequencies to
10MHz. They feature 35
max on-resistance, 7 on-
resistance matching between channels, 5
on-resis-
tance flatness, and as low as 0.07% total harmonic
distortion.
