Product details
Overview
MAX9291GTN/VY+ from Analog Devices is a 3.12Gbps GMSL serializer that converts HDMI 1.4a input (with integrated equalizer, DDC, and termination) into a serialized video/audio/control link over 50Ω coax or 100Ω STP cable up to 15m. It supports 104MHz pixel clock (1920×720p/60Hz, 24-bit color), 32kHz–192kHz audio sampling, and programmable 100–500mV SE / 100–400mV diff output amplitude. Used in automotive rear-seat infotainment systems requiring robust EMI suppression and high-immunity control channel operation.
For engineers reviewing the MAX9291GTN/VY+ datasheet, MAX9291GTN/VY+ pinout, MAX9291GTN/VY+ application, or MAX9291GTN/VY+ equivalent, key selection factors include HDMI-to-GMSL conversion capability, coax/STP output flexibility, spread-spectrum EMI reduction, -40°C to +105°C automotive qualification, and UART/I2C reverse control channel support up to 1Mbps.
Technical Context
The MAX9291GTN/VY+ implements a full GMSL serializer with HDMI 1.4a receiver front-end, supporting RGB/YUV video mapping, embedded audio extraction (L-PCM I2S stereo or 8-channel TDM), and bidirectional control channel (UART-to-UART, UART-to-I2C, I2C-to-I2C). Its pre/deemphasis engine enables reliable 15m transmission at 3.12Gbps over low-cost coax.
It features dedicated hardware for HDCP-related signaling (though MAX9291 lacks encryption-only MAX9293 includes HDCP), high-immunity reverse control mode, PRBS-based BER testing, and configurable device addressing (9 default options). Core supply is 1.8V/3.3V; I/O voltage range is 1.7V–3.6V.

FAQ
What is the primary function of the MAX9291GTN/VY+?
The MAX9291GTN/VY+ is a GMSL serializer that converts HDMI 1.4a input signals-including video, audio, and control data-into a high-speed serialized stream for transmission over coax or STP cables up to 15 meters. It does not implement HDCP encryption (unlike MAX9293), but provides full HDMI receiver functionality, programmable output drive, and robust reverse control channel support. The MAX9291GTN/VY+ enables compact, noise-immune video links in automotive infotainment and ADAS systems.
Does the MAX9291GTN/VY+ support both coaxial and shielded twisted-pair (STP) cable outputs?
Yes, the MAX9291GTN/VY+ supports both 50Ω coax and 100Ω STP output configurations. Output amplitude is programmable: 100–500mV single-ended for coax, or 100–400mV differential for STP. When configured for STP, it maintains backward compatibility with legacy GMSL deserializers. The MAX9291GTN/VY+ also includes programmable pre/deemphasis to compensate for cable loss, ensuring signal integrity at full 3.12Gbps bit rate over 15m.
What audio formats and sample rates does the MAX9291GTN/VY+ support?
The MAX9291GTN/VY+ supports L-PCM audio in I2S stereo or 8-channel TDM mode, with sample rates from 32kHz to 192kHz and sample depth up to 32 bits. Audio is extracted directly from HDMI input streams or accepted via external I2S interface. The MAX9291GTN/VY+ handles HDMI TDM channel allocation per defined infoframe mapping and supports zero-padding for non-native word lengths - enabling full 7.1-channel HD audio transport alongside video without external audio processors.
How does the MAX9291GTN/VY+ handle control channel communication?
The MAX9291GTN/VY+ implements a bidirectional reverse control channel operating at 9.6kbps to 1Mbps in UART-to-UART, UART-to-I2C, or I2C-to-I2C modes, including clock-stretch capability. This allows a host microcontroller to read/write registers of the serializer, paired deserializer, or downstream peripherals at any time - independent of video timing. The MAX9291GTN/VY+ also supports high-immunity mode to reject noise in electrically harsh automotive environments.
Is the MAX9291GTN/VY+ qualified for automotive applications?
Yes, the MAX9291GTN/VY+ is fully qualified for automotive use with guaranteed operation from -40°C to +105°C ambient temperature. It meets ISO 10605 (±8kV contact, ±15kV air) and IEC 61000-4-2 ESD standards, and its design targets ASIL-B functional safety requirements in video signal paths. The MAX9291GTN/VY+ is packaged in a thermally enhanced 56-pin TQFN with exposed pad, optimized for automotive PCB thermal management and mechanical reliability.
