Figure 1. I
The MAX9132/MAX9134/MAX9135 high-speed, multi-
ple-port, low-voltage differential signaling (LVDS)
crossbar switches are specially designed for digital
video and camera signal transmission. These switches
have a wide bandwidth, supporting data rates up to
840Mbps. This allows the use of MAX9132/MAX9134/
MAX9135 with LVDS serializers/deserializers (SerDes)
to create a complete video or camera network. The
MAX9132 has three input ports and two output ports,
the MAX9134 has three input ports and four output
ports, and the MAX9135 has four input ports and three
output ports. The video or camera signal can go
through the switch from an input port to one or multiple
output ports.
The MAX9132/MAX9134/MAX9135 switch routing is
programmable through either an I
Local Interconnect Network (LIN) serial interface. AS0
and AS1 set the slave addresses for either of these
modes, allowing several devices on a bus simultane-
ously. In addition, the MAX9134/MAX9135 provide
3-level pins S[5:0] to set switch routing and the initial
conditions for I
all the LVDS outputs feature selectable preemphasis.

On power-up, all control registers have a value of 0x00.
For the MAX9134/MAX9135, leaving S[5:0] unconnect-
ed, allows control through the LIN interface with all out-
puts deactivated. Otherwise, the switch runs in
pin-control mode with S[5:0] controlling the switch rout-
ing. The I

the pin settings. For more details, see the I
section. For the MAX9132, the FS input determines
which interface is active.
There are four 1-byte control registers in the
MAX9132/MAX9134/MAX9135. These registers control
the routing of the switch. Table 1 describes the register
map for both I
MAX9134/MAX9135 operate in LIN mode, register 0x00
acts as an error flag register. Its function is described
in detail in Table 5. In either I
trol registers (0x01, 0x02) program the MAX9132/
MAX9134/MAX9135 switch routing control. In addition,
these registers can individually activate and deactivate
preemphasis for each output port. Table 2a describes
the routing for the MAX9132/MAX9134 and Table 2b for
the MAX9135. For I
