MAX9268 19-5211 Rev 2 1/11 Gigabit Multimedia Serial Link Deserializer with LVDS System Interface General Description Features The MAX9268 deserializer utilizes Maxims gigabit S Pairs with Any GMSL Serializer multimedia serial link (GMSL) technology. The MAX9268 S 2.5Gbps Payload-Rate AC-Coupled Serial Link deserializer features an LVDS system interface for reduced S Scrambled 8b/10b Line Coding pin count and a smaller package, and pairs with any GMSL S Supports WXGA (1280 x 800) with 24-Bit Color serializer to form a complete digital serial link for joint transmission of high-speed video, audio, and bidirectional S 8.33MHz to 104MHz (3-Channel LVDS) or 6.25MHz control data. to 78MHz (4-Channel LVDS) Output Clock The MAX9268 allows a maximum serial payload data 2 S 4-Bit to 32-Bit Word Length, 8kHz to 192kHz I S rate of 2.5Gbps for a 15m shielded twisted-pair (STP) Audio Channel Supports High-Definition Audio cable. The deserializer operates up to a maximum S Embedded Half-/Full-Duplex Bidirectional Control output clock rate of 104MHz (3-channel LVDS) or 78MHz Channel (100kbps to 1Mbps) (4-channel LVDS). This serial link supports display S Two 3-Level Inputs Support 9 Device Addresses panels from QVGA (320 x 240) to WXGA (1280 x 800) and higher with 24-bit color. S Interrupt Supports Touch-Screen Functions for Display Panels The 3-channel mode outputs an LVDS clock, three lanes 2 of LVDS data (21 bits), UART control signals, and one I S 2 S I C Master for Peripherals audio channel consisting of three signals. The 4-channel S Equalizer for Serial Link Input mode outputs an LVDS clock, four lanes of LVDS data 2 S Programmable Spread Spectrum on the LVDS and (28 bits), UART control signals, an I S audio channel, Control Outputs for Reduced EMI and auxiliary control outputs. The three audio outputs 2 form a standard I S interface, supporting sample rates S Serial-Data Clock Recovery Eliminates an External from 8kHz to 192kHz and audio word lengths of 4 to 32 Clock bits. The embedded control channel forms a full-duplex, S Automatic Data-Rate Detection Allows On-the-Fly differential, 100kbps to 1Mbps UART link between the Data-Rate Change serializer and deserializer. An electronic control unit (ECU), S Built-In PRBS Generator for BER Testing of the or microcontroller (FC), can be located on the serializer Serial Link side of the link (typical for video display), on the MAX9268 side of the link (typical for image sensing), or on both sides. S ISO 10605 and IEC 61000-4-2 ESD Protection In addition, the control channel enables ECU/FC control of S -40NC to +105NC Operating Temperature Range peripherals on the remote side, such as backlight control, S 1.8V to 3.3V I/O and 3.3V Core Supplies grayscale gamma correction, camera module, and touch screen. Base-mode communication with peripherals uses S Patent Pending 2 either I C or the GMSL UART format. In addition, the Ordering Information MAX9268 features a bypass mode that enables full-duplex communication using custom UART formats.
