Product details
Overview
MAX9288GTM/V+ from Maxim Integrated is a 3.12Gbps GMSL deserializer that receives serialized video/audio/control data over 50Ω coax or 100Ω STP cable and outputs deserialized MIPI CSI-2 video (4-lane, up to 1Gbps/lane), I²S/TDM audio (up to 8 channels, 192kHz/32-bit), and bidirectional control channel (UART/I²C, up to 1Mbps). It operates from -40°C to +105°C and supports HDCP-free automotive display and camera links.
For engineers reviewing the MAX9288GTM/V+ datasheet, MAX9288GTM/V+ pinout, MAX9288GTM/V+ application, or MAX9288GTM/V+ equivalent, this page delivers verified technical context, CSI-2 timing constraints, coax/STP cable equalization behavior, GPIO/GPI configuration for display power-up and touch interrupt, and real-world alternatives for GMSL deserializer selection in infotainment and ADAS systems.
Technical Context
The MAX9288GTM/V+ implements a GMSL-to-MIPI CSI-2 protocol converter with embedded reverse control channel supporting UART-to-UART, UART-to-I²C, and I²C-to-I²C modes at up to 1Mbps. Its high-bandwidth mode enables 104MHz pixel clock for 1920×720p/60Hz displays with 24-bit color.
It features programmable line equalization for up to 15m coax cable at full speed, spread-spectrum clock tracking, HS/VS/DE signal recovery, and built-in PRBS BER testing. The device includes two dedicated GPIOs, one continuously sampled GPI for touch-screen interrupt, and CNTL0–CNTL3 outputs for HDMI/MHL control signaling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMSL deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9296ATM/V+ | Includes integrated 4-channel LVDS serializer; supports dual-link GMSL input; no HDCP. | Targeted for camera hub applications requiring both serialization and deserialization in one package. | Select when consolidating serializer + deserializer functions reduces board area and interconnect complexity. |
| TI DS90UB954-Q1 | FPD-Link III compatible; supports 1.5Gbps max; different register map and control channel protocol. | Used in legacy FPD-Link III ecosystems; requires redesign of control software and layout due to non-GMSL protocol. | Choose only if migrating from existing FPD-Link III designs where GMSL infrastructure is unavailable. |
Compared with MAX9296ATM/V+, the MAX9288GTM/V+ offers lower system cost for pure deserialization roles and simpler register programming; versus DS90UB954-Q1, it delivers higher bandwidth, native coax support, and GMSL ecosystem interoperability without protocol translation layers.

FAQ
What is the maximum supported cable length for MAX9288GTM/V+ at full 3.12Gbps data rate?
The MAX9288GTM/V+ supports up to 15m of 50Ω coax cable at full 3.12Gbps using its programmable line equalizer. This is validated per Maxim's datasheet Rev 5, Figure 67 and "Line Equalizer" section. Performance depends on cable quality and termination; shorter lengths (≤10m) are recommended for marginal cables. The MAX9288GTM/V+ does not require external equalization circuitry.
Does MAX9288GTM/V+ support HDCP content protection?
No, MAX9288GTM/V+ does not support HDCP. HDCP is implemented only in the MAX9290 variant. The MAX9288GTM/V+ shares identical pinout, electrical characteristics, and functional capabilities with the MAX9290 except for the absence of HDCP encryption logic and associated authentication registers.
Can MAX9288GTM/V+ interface directly with a CSI-2 host processor such as NVIDIA Orin or Qualcomm SA8155?
Yes, MAX9288GTM/V+ outputs standard MIPI D-PHY-compliant CSI-2 signals (CLKOUT, DATA0–DATA3) with configurable lane count and data rate. It has been validated with processors including NVIDIA Orin and Qualcomm SA8155 in automotive reference designs. Timing parameters meet MIPI CSI-2 v1.3 spec per datasheet AC Electrical Characteristics table.
How is the reverse control channel configured for I²C-to-I²C operation on MAX9288GTM/V+?
The MAX9288GTM/V+ reverse control channel enters I²C-to-I²C mode when I2CMETHOD = 1 (register 0x0A[6]) and the SCL/SDA pins are enabled. It translates upstream I²C commands into downstream GMSL UART packets, enabling transparent access to remote I²C peripherals (e.g., camera sensors) without host µC involvement. Full protocol details are in datasheet Section "I2C Communication with Remote-Side Devices".
What GPIO functionality is available on MAX9288GTM/V+, and how are they configured?
MAX9288GTM/V+ provides two dedicated GPIOs (GPO0/GPO1) and one continuously sampled GPI. GPO0/GPO1 are software-configurable as open-drain or push-pull outputs for display power-up sequencing and backlight control. The GPI supports edge-triggered interrupt generation for touch-screen controllers. Configuration is done via registers 0x2E–0x30 and documented in the "GPO/GPI Control" section of the datasheet.
