Detailed Desc ription
The MAX4357 is a highly integrated 32
16 nonblock-
ing video crosspoint switch matrix. All inputs and out-
puts are buffered, with all outputs able to drive
standard 75
reverse-terminated video loads.
A three-wire interface programs the switch matrix and
initializes with a single update signal. The unique serial
interface operates in one of two modes, Complete
Matrix Mode (Mode 1) or Individual Output Address
Mode (Mode 0).
The signal path of the MAX4357 is from the buffered
inputs (IN0
–
IN31), through the switching matrix,
buffered by the output amplifiers, and presented at the
outputs (OUT0
–
OUT15) (
Functional Diagram
). The
other functional blocks are the serial interface and con-
trol logic. Each of the functional blocks is described in
detail in the sections following.
Analog Outputs
The MAX4357 outputs are high-speed amplifiers capa-
ble of driving 150
(75
back-terminated) loads. The
gain, A
V
= +1V/V or +2V/V, is selectable through pro-
gramming bit 5 of the serial control word. Amplifier
compensation is automatically optimized to maximize
the bandwidth for each gain selection. Each output can
be individually enabled and disabled through bit 6 of
the serial control word. When disabled, the output is
high impedance presenting typically 4k
load, and 3pF
output capacitance, allowing multiple outputs to be
connected together for building large arrays. On
power-up (or asynchronous
RESET
), all outputs are ini-
tialized in the disabled state to avoid output conflicts in
large array configurations. The programming and oper-
ation of the MAX4357 is output referred. Outputs are
configured individually to connect to any one of the 32
analog inputs, programmed to the desired gain (A
V
=
+1V/V or +2V/V), and enabled or disabled in a high-
impedance state.
