MAX9296A datasheet
General Description
The MAX9296A
deserializer converts single or dual serial
inputs to MIPI CSI-2 outputs. The device operates in either
GMSL1 or GMSL2 mode. The MAX9296A
also sends and
receives side-channel data, enabling full-duplex transmis
-
sion of forward path video and bidirectional control data
over
low-cost
50Ω
coax
or
100Ω
STPcables
to
meet
the
GMSL2 or GMSL1 channel specification.
The GMSL2 links operate at a fixed rate of 3Gbps or
6Gbps in the forward direction and 187.5Mbps in the
reverse direction. In GMSL1 mode, each serial link can
be paired with 3.12Gbps or 1.5Gbps GMSL1 serializ
-
ers or operate up to 4.5Gbps with GMSL2 serializers. The
MAX9296A
supports mixed GMSL2 and GMSL1 links.
The serial inputs operate independently
, allowing videos
with different timings and resolutions to be received on
each input.
Video data from both inputs can be aggregated for output
on a single CSI-2 port or replicated on a second port for
redundant processing.
Each four-lane CSI-2 port can be programmed to oper
-
ate with any number of active data lanes. Each CSI-2
port supports 16 virtual channels and allows virtual chan
-
nel and data type reassignment.
In GMSL1 and GMSL2 modes, the side-channel oper
-
ates at 9.6kbps to 1Mbps in UART
-to-UAR
T mode,
and 9.6kbps to 1Mbps in I
2
C-to-I
2
C mode with clock
stretching. Using the side-channel, a µC residing on
either end of the link can program serializer
, deserializer
,
and peripheral device registers independent of video tim
-
ing. In GMSL2 mode, two additional pass-through I
2
C or
UART
channels and a pass-through 50MHz SPI channel
provides peripheral control.
The MAX9296A
operates over the automotive tempera
-
ture range of -40°C to +105°C and is
AEC-Q100 qualified.

Absolute Maximum Ratings
Stresses
beyond
those
listed
under
“Absolute Maximum
Ratings”
may
cause
permanent
damage
to
the
device.
These
are
stress
ratings
only
,
and
functional
operation
of
the
device
at
these
or any
other conditions beyond
those indicated in
the operational sections
of the
specifications is not
implied. Exposure to
absolute maximum rating
conditions for
extended periods may
affect
device reliability
.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
