Product details
Overview
MAX9282AGTM/V+ from Maxim Integrated is a 3.12Gbps GMSL deserializer for automotive infotainment and camera links, supporting HDCP-encrypted video over 50Ω coax or 100Ω STP cable, delivering up to 1920×720p/60Hz with 24-bit color, 192kHz/32-bit audio in TDM mode, and operating from -40°C to +105°C.
For engineers reviewing the MAX9282AGTM/V+ datasheet, MAX9282AGTM/V+ pinout, MAX9282AGTM/V+ application, or MAX9282AGTM/V+ equivalent, key selection factors include coax/STP input compatibility, HDCP content protection, embedded UART/I2C control channel (up to 1Mbps), programmable cable equalization for 15m full-speed operation, and LVDS output timing compliance with automotive display interfaces.
Technical Context
The MAX9282AGTM/V+ implements a CDR-based serial link receiver with integrated HDCP decryption engine, supporting high-bandwidth mode (104MHz pixel clock) and dual-mode audio transport (I2S stereo or 8-channel TDM). Its reverse control channel operates in UART-to-UART, UART-to-I2C, or I2C-to-I2C modes with clock-stretch capability.
It features a 7x PLL architecture for serial bit recovery, configurable spread-spectrum LVDS outputs, and a dedicated GPI input for touch-screen interrupt handling. The device includes built-in PRBS BER testing, nine programmable default I2C addresses, and high-immunity reverse control-channel mode for noise rejection in harsh automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMSL deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9278A | No HDCP support; otherwise pin- and function-compatible with MAX9282AGTM/V+. | Suitable for non-encrypted video paths (e.g., backup camera feed to non-HDCP display). | Select when content protection is unnecessary and cost optimization is prioritized. |
| TI DS90UB928QSQ | FPD-Link III compatible; different register map, no built-in LUT or PRBS tester; requires external HDCP engine. | Used in FPD-Link III ecosystems; lacks native gamma correction and integrated BER test capability. | Choose only when migrating from existing TI-based designs with matching layout and firmware infrastructure. |

FAQ
What is the primary function of the MAX9282AGTM/V+ in an automotive video system?
The MAX9282AGTM/V+ 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 parallel LVDS video (oLDI) and I2S/TDM audio for display or processing. It serves as the critical interface between centralized video sources and distributed displays or camera modules in modern automotive architectures.
Does the MAX9282AGTM/V+ support both coaxial and shielded twisted-pair (STP) cable inputs?
Yes, the MAX9282AGTM/V+ supports both 50Ω coaxial and 100Ω shielded twisted-pair (STP) cable inputs. It automatically detects cable type using ADD[1:0] configuration pins and maintains backward compatibility with earlier GMSL serializers when configured for STP mode. This dual-input flexibility simplifies design reuse across different vehicle platforms and harness architectures.
How does the MAX9282AGTM/V+ handle HDCP content protection?
The MAX9282AGTM/V+ integrates a full HDCP 1.4 decryption engine, enabling secure playback of encrypted video streams from GMSL serializers. It supports repeater functionality, authentication handshaking, and synchronization of encryption keys across downstream links. HDCP operation is managed entirely through the embedded control channel, allowing microcontroller-based control without interrupting video flow.
What audio formats and sample rates does the MAX9282AGTM/V+ support?
The MAX9282AGTM/V+ supports L-PCM I2S stereo and up to eight channels of L-PCM in TDM mode, with sample rates ranging from 32kHz to 192kHz and sample depths up to 32 bits. Audio clock can be sourced from either the audio transmitter (source) or receiver (sink), providing flexible clock domain management in complex multi-processor automotive audio systems.
Can the MAX9282AGTM/V+ be used without an external microcontroller for basic operation?
Yes, the MAX9282AGTM/V+ supports autonomous operation using its internal configuration logic and default register settings. Basic video deserialization works immediately upon power-up with default device address and cable-type detection. However, full feature utilization-including HDCP, LUT programming, spread-spectrum control, and GPIO configuration-requires microcontroller interaction via the I2C or UART control channel.
