Product details
Overview
MAX9293BGTN/V+ from Analog Devices is a GMSL serializer IC that converts HDMI 1.4a input to a 3.12Gbps gigabit multimedia serial link for video/audio/control transmission over 15m+ of 50Ω coax or 100Ω STP cable. It integrates HDCP content protection, supports 104MHz pixel clock (1920×720p/60Hz), 192kHz/32-bit audio, and programmable pre/deemphasis. Used in automotive rear-seat infotainment systems with FAKRA connectors.
For engineers reviewing the MAX9293BGTN/V+ datasheet, MAX9293BGTN/V+ pinout, MAX9293BGTN/V+ application, or MAX9293BGTN/V+ equivalent, key selection criteria include HDCP support, coax/STP output flexibility, GMSL reverse control channel capability, spread-spectrum EMI reduction, and -40°C to +105°C automotive qualification.
Technical Context
The MAX9293BGTN/V+ implements a full GMSL serializer with HDMI 1.4a receiver front-end including DDC, HPD, EDID, and integrated input equalizer. It supports dual-mode serial output-programmable 100–500mV single-ended (coax) or 100–400mV differential (STP)-and embeds a bidirectional UART/I2C control channel operating up to 1Mbps.
Its architecture includes an embedded PRBS generator for BER testing, dedicated GPO for touch-screen interrupt signaling, and configurable sleep/wake-up via local or remote request. HDCP 1.4 encryption is hardware-accelerated and managed through the control channel, distinguishing it functionally from the non-HDCP MAX9291.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Serial Bit Rate | Up to 3.12Gbps - enables uncompressed HD video transport over single coax/STP cable without multiplexing overhead. |
| HDMI Input | HDMI 1.4a compliant with integrated DDC, HPD, EDID, and input termination - eliminates need for external level shifters or buffers. |
| Audio Support | L-PCM I2S stereo or 8-channel TDM up to 192kHz/32-bit - meets automotive surround sound and ADAS audio logging requirements. |
| Control Channel | UART-to-UART, UART-to-I2C, or I2C-to-I2C at 9.6kbps–1Mbps with clock-stretch capability - allows real-time register access independent of video timing. |
| Operating Temp | -40°C to +105°C - qualified for under-hood and display-module mounting in passenger vehicles per AEC-Q100 stress test profile. |
| ESD Protection | ±8kV contact / ±15kV air per ISO 10605 and IEC 61000-4-2 - ensures robustness against assembly handling and in-vehicle transients. |
| Supply Voltages | Core: 1.8V & 3.3V; I/O: 1.7V–3.6V - supports mixed-voltage system integration with common automotive power rails. |
Pinout & Package
MAX9293BGTN/V+ uses a lead(Pb)-free, 56-pin, 8mm × 8mm TQFN/SWTQFN package with exposed thermal pad and 0.5mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT+, OUT- | Differential serial output | Drives 100Ω STP; amplitude programmable 100–400mV differential - enables noise-immune long-cable links. |
| OUT | Single-ended serial output | Drives 50Ω coax; amplitude programmable 100–500mV - compatible with low-cost FAKRA connectors. |
| HDMI_RX[0:23] | HDMI data bus inputs | Accepts TMDS-level signals directly; internal termination and equalization reduce external component count. |
| HPD, DDC_SCL, DDC_SDA | HDMI hot-plug detect & display data channel | Full DDC interface with pull-up support - enables automatic EDID read and source detection without µC intervention. |
| GPO | General-purpose output | Dedicated interrupt line for touch-screen controller - reduces polling overhead and improves system responsiveness. |
| RXC_, TXC_ | Reference clock input/output | Supports spread-spectrum tracking and synchronization between serializer/deserializer - critical for jitter-sensitive video timing. |
Key Features
| Feature | Design Value |
|---|---|
| HDCP 1.4 Hardware Engine | On-chip encryption/decryption logic enables secure video path without external crypto IC or firmware overhead. |
| Programmable Pre/Deemphasis | Compensates for high-frequency loss in long coax/STP cables - maintains signal integrity at full 3.12Gbps over 15m. |
| Spread-Spectrum Output | Reduces peak EMI by >10dB across 30–1000MHz - simplifies EMC compliance in crowded automotive harness environments. |
| High-Immunity Reverse Control Mode | Enables reliable UART/I2C communication over noisy cables even at 1Mbps - avoids retransmission and latency spikes. |
| Built-in PRBS Generator | Permits in-system bit-error-rate validation without external test equipment - accelerates production line functional testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMSL serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9291GTN/V+ | No HDCP engine; identical pinout, timing, and serial interface - differs only in encryption capability and associated registers. | Suitable for non-content-protected displays (e.g., instrument clusters, backup cameras) where HDCP licensing is unnecessary. | Select MAX9291GTN/V+ when video security is not required and cost optimization is prioritized. |
| DS90UB925QSQ/NOPB | FPGA-compatible 1.5Gbps FPD-Link III serializer; different protocol stack, no native HDMI input - requires external HDMI-to-LVCMOS bridge. | Used in legacy TI-based ADAS platforms; lacks integrated DDC/EDID and HDCP, but offers lower power and smaller footprint. | Choose DS90UB925QSQ/NOPB only when migrating from existing FPD-Link III designs and HDMI receiver functionality is handled externally. |
Compared with MAX9291GTN/V+, the MAX9293BGTN/V+ adds mandatory HDCP 1.4 hardware for premium content delivery, while DS90UB925QSQ/NOPB requires external HDMI interface components and provides no built-in content protection - making MAX9293BGTN/V+ the sole drop-in solution for certified automotive HDMI sink applications.

FAQ
Does MAX9293BGTN/V+ support both coaxial and shielded twisted-pair (STP) cable outputs?
Yes, MAX9293BGTN/V+ supports both output types: single-ended 100–500mV drive for 50Ω coax and differential 100–400mV drive for 100Ω STP. The output mode is selected via configuration registers, and the same MAX9293BGTN/V+ device can be deployed interchangeably in either topology without hardware change.
What is the maximum HDMI pixel clock supported by MAX9293BGTN/V+?
MAX9293BGTN/V+ supports up to 104MHz pixel clock in high-bandwidth mode, enabling 1920×720p/60Hz display resolution with 24-bit color depth. This timing is validated per HDMI 1.4a specification and confirmed in the MAX9293BGTN/V+ datasheet AC Electrical Characteristics table.
Is MAX9293BGTN/V+ pin-compatible with MAX9291GTN/V+?
Yes, MAX9293BGTN/V+ is pin-compatible and footprint-compatible with MAX9291GTN/V+. Both share identical 56-pin TQFN packaging, pin assignments, power sequencing, and interface timing - differing only in HDCP-related internal logic and associated register bits.
How does the reverse control channel operate on MAX9293BGTN/V+?
The MAX9293BGTN/V+ reverse control channel operates at 9.6kbps–1Mbps in UART-to-UART, UART-to-I2C, or I2C-to-I2C modes with clock-stretch capability. It allows a microcontroller to program serializer, deserializer, and peripheral registers at any time - even during active video transmission - and manage HDCP authentication independently of video timing.
What ESD protection level does MAX9293BGTN/V+ provide on its serial output pins?
MAX9293BGTN/V+ provides ±8kV contact and ±15kV air discharge ESD protection on all pins per ISO 10605 and IEC 61000-4-2 standards. This rating applies directly to the OUT+, OUT-, and OUT pins and is verified in the Absolute Maximum Ratings section of the MAX9293BGTN/V+ datasheet.
