Detailed Desc ription
The MAX4356 is a highly integrated 16
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 3-wire interface programs the switch matrix and ini-
tializes 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).
In the
Functional Diagram,
the signal path of the
MAX4356 is from the inputs (IN0
–
IN15), through the
switching matrix, buffered by the output amplifiers, and
presented at the output terminals (OUT0
–
OUT15). The
other functional blocks are the serial interface and con-
trol logic. Each of the functional blocks is described in
detail below.
Analog Outputs
The MAX4356 outputs are high-speed voltage feed-
back amplifiers capable of driving 150
(75
back-ter-
minated) loads. The gain, A
V
= +1V/V or +2V/V, is
selectable through programming bit 4 of the serial con-
trol word. Amplifier compensation is automatically opti-
mized to maximize the bandwidth for each gain selec-
tion. Each output can be individually enabled and dis-
abled through bit 5 of the serial control word. When
disabled, the output is high impedance, presenting typ-
ically a 4k
load, and 3pF output capacitance, allowing
multiple outputs to be connected together in building
large arrays. On power-up (or asynchronous
RESET
),
all outputs are initialized in the disabled state to avoid
output conflicts in large array configurations. The pro-
gramming and operation of the MAX4356 is output
referred. Outputs are configured individually to connect
to any one of the 16 analog inputs, programmed to the
desired gain (A
V
= +1V/V or +2V/V), or disabled in a
high-impedance state.
Analog Inputs
The MAX4356 offers 16 analog input channels. Each
input is buffered before the crosspoint switch matrix,
allowing one input to cross-connect to up to 16 outputs.
The input buffers are voltage feedback amplifiers with
high input impedance and low-input bias current. This
allows the use of very simple input clamp circuits.
