Detailed Description
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, AV = +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 (AV = +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.
