Gigabit Multimedia Serial Link Deserializer
with LVDS System Interface
General Description
The MAX9268 deserializer utilizes Maxim’s gigabit
multimedia serial link (GMSL) technology. The MAX9268
deserializer features an LVDS system interface for reduced
pin count and a smaller package, and pairs with any GMSL
serializer to form a complete digital serial link for joint
transmission of high-speed video, audio, and bidirectional
control data.
The MAX9268 allows a maximum serial payload data
rate of 2.5Gbps for a 15m shielded twisted-pair (STP)
cable. The deserializer operates up to a maximum
output clock rate of 104MHz (3-channel LVDS) or 78MHz
(4-channel LVDS). This serial link supports display
panels from QVGA (320 x 240) to WXGA (1280 x 800) and
higher with 24-bit color.
The 3-channel mode outputs an LVDS clock, three lanes
of LVDS data (21 bits), UART control signals, and one I2S
audio channel consisting of three signals. The 4-channel
mode outputs an LVDS clock, four lanes of LVDS data
(28 bits), UART control signals, an I2S audio channel,
and auxiliary control outputs. The three audio outputs
form a standard I2S interface, supporting sample rates
from 8kHz to 192kHz and audio word lengths of 4 to 32
bits. The embedded control channel forms a full-duplex,
differential, 100kbps to 1Mbps UART link between the
serializer and deserializer. An electronic control unit (ECU),
or microcontroller (FC), can be located on the serializer
side of the link (typical for video display), on the MAX9268
side of the link (typical for image sensing), or on both sides.
In addition, the control channel enables ECU/FC control of
peripherals on the remote side, such as backlight control,
grayscalewww.DataSheet4U.net gamma correction, camera module, and touch
screen. Base-mode communication with peripherals uses
either I2C or the GMSL UART format. In addition, the
MAX9268 features a bypass mode that enables full-duplex
communication using custom UART formats.
The GMSL serializer driver preemphasis, along with the
MAX9268 channel equalizer, extends the link length and
enhances the link reliability. Spread spectrum is available
to reduce EMI on the LVDS and control outputs of the
MAX9268. The serial line inputs comply with ISO 10605 and
IEC 61000-4-2 ESD protection standards.
The core supply for the MAX9268 is 3.3V. The I/O supply
ranges from 1.8V to 3.3V. The MAX9268 is available in
a 48-pin TQFP package (7mm x 7mm) with an exposed
pad, and is specified over the -40NC to +105NC automotive
temperature range.
