Product details
Overview
MAX9282BGTM/V+T from Maxim Integrated is a 3.12Gbps GMSL deserializer with HDCP decryption, designed for automotive infotainment and camera links. It receives serialized video/audio over 50Ω coax or 100Ω STP, outputs deserialized LVDS data on three of four lanes, supports up to 192kHz/32-bit audio in TDM mode, and operates from -40°C to +105°C for rear-seat displays and megapixel camera systems.
For engineers reviewing the MAX9282BGTM/V+T datasheet, MAX9282BGTM/V+T pinout, MAX9282BGTM/V+T application, or MAX9282BGTM/V+T equivalent, key selection factors include HDCP 1.4 compliance, programmable cable equalization for 15m coax, 104MHz high-bandwidth mode (1920×720p/60Hz), LVDS output spread spectrum, and dual GPIO/GPI support for display power-up and touch-interrupt handling.
Technical Context
The MAX9282BGTM/V+T implements a CDR-based serial link receiver with integrated HDCP 1.4 decryption engine, supporting both UART-to-UART and I2C-to-I2C reverse control channel modes up to 1Mbps. Its 7x PLL architecture enables precise pixel clock recovery and HS/VS/DE tracking for timing-critical display interfaces.
It features a configurable line equalizer with 12 programmable boost levels, a built-in PRBS BER tester, and a color lookup table (LUT) for gamma correction. The device supports high-immunity reverse control-channel mode and fast lock-time synchronization for camera frame sync applications.

FAQ
What is the primary function of the MAX9282BGTM/V+T in an automotive system?
The MAX9282BGTM/V+T functions as a gigabit multimedia serial link (GMSL) deserializer that receives high-speed serialized video and audio over coax or STP cable, decrypts HDCP-protected content, and outputs deserialized LVDS video data with recovered timing signals. It serves as the interface between GMSL serializers (e.g., in cameras or head units) and display processors or FPGAs in automotive applications such as rear-seat infotainment and ADAS camera systems.
Does the MAX9282BGTM/V+T support both coaxial and shielded twisted-pair (STP) cable inputs?
Yes, the MAX9282BGTM/V+T supports both 50Ω coaxial and 100Ω shielded twisted-pair (STP) cable inputs. When configured for STP, it maintains backward compatibility with legacy GMSL serializers. Its programmable cable equalizer adapts to varying cable lengths and losses, enabling reliable operation up to 15m at full 3.12Gbps data rate on coax.
How does the MAX9282BGTM/V+T handle audio transport and clocking?
The MAX9282BGTM/V+T supports L-PCM audio in I2S stereo or 8-channel TDM format, with sample rates from 32kHz to 192kHz and sample depths up to 32 bits. It offers flexible audio clocking: MCLK can be sourced from either the audio sink (display side) or audio source (head unit), and includes dedicated outputs for WS, SCK, and SD to drive external DACs or audio processors without additional clock generation circuitry.
What role does the reverse control channel play in the MAX9282BGTM/V+T?
The reverse control channel in the MAX9282BGTM/V+T enables bidirectional communication over the same physical cable used for video transport. Operating at up to 1Mbps in UART-to-UART, UART-to-I2C, or I2C-to-I2C modes, it allows a local microcontroller to configure the deserializer, upstream serializer, and connected peripherals (e.g., camera sensors, touch controllers) without requiring separate control wiring-reducing harness complexity and EMI susceptibility.
Is the MAX9282BGTM/V+T qualified for automotive temperature and reliability standards?
Yes, the MAX9282BGTM/V+T is rated for -40°C to +105°C operation and meets AEC-Q100 stress-test requirements. It incorporates ±8kV contact and ±15kV air ESD protection per ISO 10605 and IEC 61000-4-2, and its TQFN package with side-wettable terminations supports automated optical inspection for high-yield automotive PCB assembly. These features ensure robust performance in demanding automotive environments.
