Product details
Overview
MAX9288GGM/VY+ 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 (up to 4 lanes × 1Gbps), L-PCM audio (up to 8-channel TDM, 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 MAX9288GGM/VY+ datasheet, MAX9288GGM/VY+ pinout, MAX9288GGM/VY+ application, or MAX9288GGM/VY+ equivalent, this page delivers verified technical context, CSI-2 timing constraints, coax/STP equalization settings, GPIO/GPI configuration for touch-interrupt and backlight control, and real-world automotive use-case validation - all grounded in Maxim's official MAX9288/MAX9290 datasheet Rev 5 (8/2019).
Technical Context
The MAX9288GGM/VY+ 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, while auto-pixel-per-line tracking maintains synchronization across variable-resolution streams.
It integrates a programmable line equalizer for up to 15m coax cable at full speed, HS/VS/DE tracking with inversion support, spread-spectrum clock tracking, and built-in PRBS BER tester. The device features two dedicated GPIOs, one dedicated "Up/Down" GPI for touch-screen interrupt, and dual µC control capability via configuration link.

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMSL deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9290GGM/VY+ | Includes HDCP 1.4 content protection; otherwise identical pinout, electrical specs, and feature set. | Required where encrypted video transport (e.g., premium media playback) is mandated; not needed for camera-only links. | Select MAX9290GGM/VY+ only when HDCP authentication and encryption are required; MAX9288GGM/VY+ suffices for non-protected video/audio. |
| TI DS90UB954-Q1 | FPGA-compatible FPD-Link III deserializer; different protocol stack, register map, and CSI-2 lane mapping (3-lane vs. 4-lane). | Used in legacy FPD-Link III ecosystems; requires redesign of serializer side and firmware adaptation. | Choose only when migrating from TI-based designs; not drop-in - protocol, timing, and control channel differ fundamentally. |
Compared with MAX9290GGM/VY+, the MAX9288GGM/VY+ omits HDCP but retains identical GMSL compatibility, equalization, and CSI-2 performance - making it optimal for cost-sensitive camera links. Against DS90UB954-Q1, it offers native GMSL interoperability and higher lane count, avoiding protocol translation overhead.

FAQ
What is the maximum supported cable length for MAX9288GGM/VY+ at full 3.12Gbps data rate?
The MAX9288GGM/VY+ supports up to 15 meters of 50Ω coax cable at full 3.12Gbps using its programmable cable equalizer. This is validated per Maxim's datasheet (p.1, "Equalization Allows 15m Cable at Full Speed") and applies to both coax and 100Ω STP configurations when properly terminated and AC-coupled.
Does MAX9288GGM/VY+ support MIPI CSI-2 D-PHY v1.2 or later?
Yes, the MAX9288GGM/VY+ outputs standard MIPI CSI-2 D-PHY compliant signals with 4 data lanes and 1 clock lane, supporting data rates up to 1Gbps per lane. Its timing parameters align with MIPI CSI-2 v1.3 specifications, including LP-to-HS transition, settle time, and skew tolerance as defined in the datasheet (p.27, Figure 13).
Can MAX9288GGM/VY+ be used without an external microcontroller?
Yes - the MAX9288GGM/VY+ supports autonomous operation via three-level configuration inputs (p.84) and default device addresses. While a µC enhances flexibility (e.g., runtime register writes), basic video/audio forwarding works without one. However, features like LUT programming, PRBS test activation, or GPIO reconfiguration require µC interaction.
What audio formats does MAX9288GGM/VY+ support on its I²S/TDM interface?
The MAX9288GGM/VY+ 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. Audio clock can be sourced from either the audio sink or source, enabling flexible system-level clock tree design as confirmed in the "Audio Channel" section (p.50–58).
Is MAX9288GGM/VY+ pin-compatible with MAX9290GGM/VY+?
Yes - MAX9288GGM/VY+ and MAX9290GGM/VY+ share identical pinout, package (48-pin TQFN), electrical characteristics, and functional behavior. The sole difference is HDCP content protection, which resides in firmware and does not affect pin assignment, timing, or power domains.
