MAX9249 19-5138 Rev 4 1/12 Gigabit Multimedia Serial Link Serializer with LVDS System Interface General Description Features S Pairs with Any GMSL Deserializer The MAX9249 serializer with LVDS system interface utilizes Maxims Gigabit multimedia serial link (GMSL) S 2.5Gbps Payload Rate AC-Coupled Serial Link technology. The MAX9249 serializer pairs with any with 8B/10B Line Coding GMSL deserializer to form a complete digital serial link S Supports Up to WXGA (1280 x 800) with 24-Bit for joint transmission of high-speed video, audio, and Color control data. S 8.33MHz to 104MHz (3-Channel LVDS) or 6.25MHz The MAX9249 allows a maximum serial payload data rate to 78MHz (4-Channel LVDS) Input Clock of 2.5Gbps for a 15m shielded twisted-pair (STP) cable. 2 S 4-Bit to 32-Bit Word Length, 8kHz to 192kHz I S The serializer operates up to a maximum clock rate of Audio Channel Supports High-Definition Audio 104MHz (3-channel LVDS) or 78MHz (4-channel LVDS). S Embedded Half-/Full-Duplex Bidirectional Control This serial link supports display panels from QVGA (320 Channel (100kbps to 1Mbps) x 240) to WXGA (1280 x 800) and higher with 24-bit color. S Interrupt Supports Touch-Screen Functions for The 3-channel mode handles three lanes of LVDS data Display Panels (21 bits), UART control signals, and three audio signals. 2 The 4-channel mode handles four lanes of LVDS data S Remote-End I C Master for Peripherals (28 bits), UART control signals, three audio signals, S Preemphasis Line Driver and/or up to three auxiliary parallel inputs. The three S Programmable Spread Spectrum on the Serial 2 audio inputs form a standard I S interface, supporting Outputs for Reduced EMI sample rates from 8kHz to 192kHz and audio word S Automatic Data-Rate Detection Allows On-the- lengths of 4 to 32 bits. The embedded control chan- Fly Data-Rate Change nel forms a full-duplex, differential, 100kbps to 1Mbps S Input Clock PLL Jitter Attenuator UART link between the serializer and deserializer. The electronic control unit (ECU), or microcontroller (FC), can S Built-In PRBS Generator for BER Testing of the be located on the MAX9249 side of the link (typical for Serial Link video display), on the deserializer side of the link (typi- S Line-Fault Detector Detects Serial Link Shorts to cal for image sensing), or on both sides. In addition, the Ground, Battery, or Open Link control channel enables ECU/FC control of peripherals S ISO 10605 and IEC 61000-4-2 ESD Protection on the remote side, such as backlight control, grayscale S -40NC to +105NC Operating Temperature Range Gamma correction, camera module, and touch screen. Base-mode communication with peripherals uses either S 1.8V to 3.3V I/O, 1.8V Core, and 3.3V LVDS 2 I C or the GMSL UART format. A bypass mode enables Supplies full-duplex communication using custom UART formats. S Patent Pending The MAX9249 serializer driver preemphasis, along with the channel equalizer on the GMSL deserializer, extends Applications the link length and enhances the link reliability. Spread High-Resolution Automotive Navigation spectrum is available on the MAX9249 to reduce EMI on Rear-Seat Infotainment the serial link and the parallel output of the GMSL dese- rializer. The serial output complies with ISO 10605 and Megapixel Camera Systems IEC 61000-4-2 ESD protection standards. Ordering Information 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 PART TEMP RANGE PIN-PACKAGE a 48-pin TQFP package (7mm x 7mm) with an exposed MAX9249GCM/V+ -40NC to +105NC 48 TQFP-EP* pad.
