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 I

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 I

and auxiliary control outputs. The three audio outputs

form a standard I

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,

grayscale gamma correction, camera module, and touch

screen. Base-mode communication with peripherals uses

either I

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.
