32 x 16 Nonblocking Video Crosspoint Switch
with On-Screen Display Insertion and I/O Buffers

Detailed Description
The MAX4358 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 MAX4358 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 below.
Analog Outputs
The MAX4358 outputs are high-speed amplifiers capa-
ble of driving 150 (75 back-terminated) loads. The
gain, AV = +1V/V or +2V/V, is selectable via program-
ming bit 5 of the serial control word. Amplifier compen-
sation is automatically optimized to maximize the
bandwidth for each gain selection. Each output can be
individually enabled and disabled via bit 6 of the serial
control word. When disabled, the output is high imped-
ance 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 initialized in the
disabled state to avoid output conflicts in large array
configurations. The programming and operation of the
MAX4358 is output referred. Outputs are configured
individually to connect to any one of the 32 analog
inputs, programmed to the desired gain (AV = +1V/V or
+2V/V), and enabled or disabled in a high-impedance
state.
