MAX9675
110MHz, 16 x 16 Video Crosspoint
Switch with Programmable Gain
______________________________________________________________________________________

Detailed Description
The MAX9675 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
Ω 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
MAX9675 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 MAX9675 outputs are high-speed voltage feedback
amplifiers capable of driving 150
Ω (75Ω back-terminat-
ed) loads. The gain, AV = +1V/V or +2V/V, is selectable
through programming bit 4 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 5 of the serial control word. When disabled, the out-
put is high impedance, presenting typically a 4k
Ω 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 ini-
tialized in the disabled state to avoid output conflicts in
large-array configurations. The programming and opera-
tion of the MAX9675 is output referred. Outputs are con-
figured 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 MAX9675 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.
