The MAX9249 serializer with LVDS system interface

utilizes Maxim’s Gigabit multimedia serial link (GMSL)

technology. The MAX9249 serializer 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 15m shielded twisted-pair (STP) cable.

The serializer operates up to a maximum 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 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 I

sample rates from 8kHz to 192kHz and audio word

lengths of 4 to 32 bits. The embedded control chan-

nel forms a full-duplex, differential, 100kbps to 1Mbps

UART link between the serializer and deserializer. The

electronic control unit (ECU), or microcontroller (FC), can

be located on the MAX9249 side of the link (typical for

video display), on the deserializer side of the link (typi-

cal 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, grayscale

Gamma correction, camera module, and touch screen.

Base-mode communication with peripherals uses either

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.

The core supply for the MAX9249 is 1.8V. The I/O supply

ranges from 1.8V to 3.3V. The MAX9249 is available in

a 48-pin TQFP package (7mm x 7mm) with an exposed

pad. Electrical performance is guaranteed over the

-40NC to +105NC automotive temperature range.
