MAX9249GCM/V+ by Analog Devices

Gigabit Multimedia Serial Link Serializer with LVDS System Interface


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 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 electronic control unit (ECU), or microcontroller (µC), can be located on the MAX9249 side of the link (typical for video display), on the deserializer side of the link (typical for image sensing), or on both sides. In addition, the control channel enables ECU/µC 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 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 deserializer. 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 -40°C to +105°C automotive temperature range.
