MAX9249
Gigabit Multimedia Serial Link
Serializer with LVDS System Interface
Detailed Description
The MAX9249 serializer with LVDS system interface
utilizes Maxim’s GMSL technology. The MAX9249 serial-
izer pairs with any GMSL deserializer to form a complete
digital serial link for joint transmission of high-speed
video, audio, and control data.
The MAX9249 allows a maximum serial payload data
rate of 2.5Gbps for a greater than 15m STP cable. The
serializer operates up to a maximum clock of 104MHz for
a 3-channel LVDS input or 78MHz for a 4-channel LVDS
input. This serial link supports display panels from QVGA
(320 x 240) up to WXGA (1280 x 800) with 24-bit color.
The 3-channel mode handles three lanes of LVDS data
(21 bits), UART control signals, and three audio signals.
The 4-channel mode handles four lanes of LVDS data
(28 bits), UART control signals, three audio signals, and/
or up to three auxiliary parallel inputs. The three audio
inputs 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. The ECU, or FC,
can be located on the MAX9249 side of the link (typical
for video display), on the deserializer side of the link (typ-
ical for image sensing), or on both sides. In addition, the
control channel enables ECU/FC control of peripherals
in the remote side, such as backlight control, grayscale
Gamma correction, camera module, and touch screen.
Base-mode communication with peripherals uses either
I2C or the GMSL UART format. A bypass mode enables
full-duplex communication using custom UART formats.
The MAX9249 serializer driver preemphasis, along with
the channel equalizer on the GMSL deserializer, extends
the link length and enhances the link reliability. Spread
spectrum is available on the MAX9249 to reduce EMI on
the serial link and the parallel output of the GMSL dese-
rializer. The serial output complies with ISO 10605 and
IEC 61000-4-2 ESD protection standards.
Register Mapping
The FC configures various operating conditions of the
MAX9249 and GMSL deserializer through internal regis-
ters. The default device addresses stored in the R0 and
R1 registers of both the MAX9249 and GSML deserial-
izer are 0x80 and 0x90, respectively. Write to the R0/R1
registers in both devices to change the device address
of the MAX9249 or GMSL deserializer.
