Product details
Overview
MAX9288GTM+ 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), stereo or 8-channel TDM audio, and bidirectional control channel traffic. It supports 1920×720p/60Hz display with 24-bit color, 192kHz/32-bit audio, and operates from -40°C to +105°C for automotive infotainment displays.
For engineers reviewing the MAX9288GTM+ datasheet, MAX9288GTM+ pinout, MAX9288GTM+ application, or MAX9288GTM+ equivalent, this page delivers verified technical context, CSI-2 timing constraints, coax/STP cable equalization behavior, HDCP-free control-channel operation, and GPIO/GPI interface design guidance specific to the MAX9288GTM+ variant.
Technical Context
The MAX9288GTM+ implements a GMSL-to-MIPI CSI-2 bridge with programmable line equalizer for up to 15m coax/STP cables, supports high-bandwidth mode at 104MHz pixel clock, and embeds UART-to-UART, UART-to-I2C, and I2C-to-I2C control channel modes up to 1Mbps with clock-stretch capability. It features auto-pixel-per-line tracking and HS/VS/DE signal recovery from serial stream.
It provides dedicated GPI for touch-screen interrupt, two GPIOs for display power-up/backlight switching, PRBS-based BER testing, and color lookup table (LUT) for gamma correction. The device uses separate supplies: 3.0–3.6V for GMSL core, 1.7–1.9V for MIPI CSI-2 I/O, and 1.7–3.6V for general I/O.

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMSL deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9296AATM+ | Includes HDCP support and enhanced spread-spectrum tracking; same pinout and CSI-2 interface. | Required where content protection is mandated (e.g., premium media playback); not needed for camera-only or non-HDCP display paths. | Select MAX9296AATM+ only if HDCP authentication and repeater support are required; otherwise MAX9288GTM+ offers lower cost and identical video/audio performance. |
| TI DS90UB954TRGCR | FPD-Link III compatible; supports different serializer pairing (e.g., DS90UB953), 1.5Gbps max serial rate, no built-in LUT. | Used in legacy FPD-Link III ecosystems; lacks native TDM audio and gamma correction-requires external audio codec and gamma IC. | Choose DS90UB954TRGCR only when migrating from existing FPD-Link III designs; MAX9288GTM+ delivers higher bandwidth, integrated audio, and display enhancement features. |
Compared with MAX9296AATM+, the MAX9288GTM+ omits HDCP but retains identical GMSL link performance, CSI-2 timing, and GPIO functionality-making it optimal for cost-sensitive camera interfaces. Against DS90UB954TRGCR, it provides 2× serial bandwidth, native 8-channel audio, and on-chip gamma correction-reducing system-level component count and layout complexity.

FAQ
What is the maximum supported cable length for MAX9288GTM+ at full 3.12Gbps data rate?
The MAX9288GTM+ supports up to 15 meters of coax or shielded twisted-pair cable at full 3.12Gbps serial bit rate using its programmable line equalizer. Performance depends on cable quality and impedance match; validated lengths assume 50Ω coax with FAKRA connectors or 100Ω STP meeting GMSL specification. For longer runs, derating or lower data rates may be required. The MAX9288GTM+ datasheet specifies equalizer settings per cable type and length.
Does MAX9288GTM+ support MIPI CSI-2 D-PHY v1.2 compliance?
Yes, the MAX9288GTM+ is fully compliant with MIPI D-PHY v1.2 specifications for its 4-lane CSI-2 output. It delivers LVDS-based differential signals with configurable swing and termination, supports data rates up to 1Gbps per lane, and meets timing parameters including setup/hold, skew, and jitter limits defined in the standard. This ensures interoperability with host processors such as NXP i.MX 8QuadMax and Renesas R-Car H3.
Can MAX9288GTM+ operate without an external microcontroller?
Yes, the MAX9288GTM+ can operate in standalone mode using its three-level configuration inputs (CFG0–CFG2) to set default device address, cable type, and data format-enabling basic video pass-through without firmware intervention. However, full feature utilization (e.g., audio routing, LUT programming, GPIO control, and error handling) requires microcontroller interaction via the embedded UART/I2C control channel.
What audio formats does MAX9288GTM+ support on its I2S/TDM interface?
The MAX9288GTM+ supports stereo L-PCM I2S and up to eight-channel L-PCM in TDM mode, with sample rates from 32kHz to 192kHz and sample depths up to 32 bits. It accepts both master and slave audio clock configurations and provides MCLK output for driving external audio codecs. Supported TDM slot counts include 2, 6, and 8 channels with flexible padding and alignment per the MAX9288GTM+ register map.
How does the MAX9288GTM+ handle loss of synchronization during video transmission?
The MAX9288GTM+ detects loss of synchronization within 1ms and asserts the ERR pin low to signal link failure. It supports fast relock without host intervention and includes auto-error-reset functionality. Frame sync (FSYNC) output remains stable during transient errors, preserving display timing integrity. Recovery behavior is configurable via registers-allowing either automatic restart or controlled halt pending MCU instruction.
