Product details
Overview
MAX9276AGTN/VY+ from Maxim Integrated is a 3.12Gbps GMSL deserializer for automotive video links, receiving serialized video/audio/control data over 50Ω coax or 100Ω STP and outputting parallel LVCMOS data. It supports 104MHz pixel clock (1920×720p/60Hz, 24-bit color), up to 192kHz/32-bit audio in TDM mode, and features programmable cable equalization for 15m full-speed operation. Used in high-resolution automotive displays and rear-seat infotainment systems.
For engineers reviewing the MAX9276AGTN/VY+ datasheet, MAX9276AGTN/VY+ pinout, MAX9276AGTN/VY+ application, or MAX9276AGTN/VY+ equivalent, key selection criteria include coax/STP input compatibility, HDCP-free operation (vs. MAX9280A), -40°C to +105°C automotive temperature range, 56-pin TQFN package with exposed pad, and support for UART/I²C reverse control channel at up to 1Mbps.
Technical Context
The MAX9276AGTN/VY+ implements a GMSL-compliant deserialization pipeline with embedded clock recovery, HS/VS/DE tracking, and configurable high-bandwidth mode for display timing alignment. Its reverse control channel operates in UART-to-UART, UART-to-I²C, or I²C-to-I²C modes with clock-stretch capability, enabling real-time register access independent of video stream timing.
It integrates a programmable line equalizer for loss compensation on long cables, spread-spectrum modulation on parallel outputs to reduce EMI, and a built-in PRBS tester for BER validation of the serial link. The device supports staggered parallel outputs and includes dedicated GPI for touch-screen interrupt signaling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMSL deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9276ATN/VY+ | Same silicon, different tape-and-reel packaging (no /VY+ suffix); identical electrical and thermal specs. | No functional difference; /VY+ denotes automotive-grade traceability and extended temperature screening. | Select MAX9276AGTN/VY+ for production programs requiring AEC-Q100 Grade 2 qualification evidence and lot-level traceability. |
| MAX9280AGTN/VY+ | Includes HDCP 1.4 content protection engine; higher core supply current during encryption; same pinout and package. | Required only when end-to-end digital rights management is mandated (e.g., OEM premium media playback). | Choose MAX9276AGTN/VY+ where HDCP is unnecessary - avoids added cost, complexity, and potential HDCP handshake delays. |
Compared with MAX9276ATN/VY+, the MAX9276AGTN/VY+ provides documented automotive traceability and screening; compared with MAX9280AGTN/VY+, it omits HDCP logic to reduce power, cost, and authentication latency - making it optimal for non-content-protected ADAS and instrumentation displays.

FAQ
What is the primary function of the MAX9276AGTN/VY+ in an automotive video system?
The MAX9276AGTN/VY+ functions as a GMSL deserializer that receives high-speed serialized video, audio, and control data over coax or STP cable and converts it into parallel LVCMOS video data (up to 24-bit), timing signals (HS/VS/DE), and auxiliary interfaces (I²C/UART). It enables compact, noise-immune video transport in automotive displays and camera systems without HDCP overhead.
Does the MAX9276AGTN/VY+ support both coaxial and shielded twisted-pair (STP) cable inputs?
Yes, the MAX9276AGTN/VY+ supports both 50Ω coaxial cable (e.g., FAKRA connectors) and 100Ω shielded twisted-pair inputs. Cable type is auto-detected or configured via hardware pins, and the internal line equalizer adapts to compensate for insertion loss - allowing seamless integration across different vehicle architectures without redesign.
How does the reverse control channel of the MAX9276AGTN/VY+ operate, and what protocols does it support?
The MAX9276AGTN/VY+ reverse control channel supports UART-to-UART, UART-to-I²C, and I²C-to-I²C modes at speeds up to 1Mbps, enabling bidirectional communication with host microcontrollers and remote peripherals. It operates independently of video timing, allowing register programming, diagnostics, and HDCP management (not applicable to MAX9276A) without disrupting the video stream.
What is the maximum supported audio format on the MAX9276AGTN/VY+?
The MAX9276AGTN/VY+ supports L-PCM audio in stereo I²S or up to eight channels in TDM mode, with sample rates from 32kHz to 192kHz and sample depths up to 32 bits. Audio clock can be derived from either source or sink, and the device includes dedicated MCLK output and flexible WS/SCK inversion for interoperability with diverse audio codecs.
Is the MAX9276AGTN/VY+ pin-compatible with the MAX9280AGTN/VY+?
Yes, the MAX9276AGTN/VY+ is pin-compatible with the MAX9280AGTN/VY+ - both use identical 56-pin TQFN packages, pin assignments, and power/signal interfaces. The only functional difference is the inclusion of HDCP logic in the MAX9280A; all other electrical, timing, and control characteristics match, enabling drop-in replacement where content protection is not required.
