Product details
Overview
MAX9295DGTM/VY+ from Analog Devices is a GMSL2 dual CSI-2 serializer with backward-compatible GMSL1 support, converting two 4-lane MIPI CSI-2 v1.3 inputs (up to 2.5Gbps/lane) into a single-wire GMSL2 serial stream at 3Gbps or 6Gbps forward / 187.5Mbps reverse. It enables full-duplex video and control transmission over coaxial or STP cables up to 20m at +105°C, targeting automotive ADAS camera links including stereo vision and side-mirror systems.
For engineers reviewing the MAX9295DGTM/VY+ datasheet, MAX9295DGTM/VY+ pinout, MAX9295DGTM/VY+ application, or MAX9295DGTM/VY+ equivalent, this page delivers verified technical context, automotive-grade thermal and EMI specifications, functional safety features (ASIL-B), cable-length-dependent bandwidth validation, and real-world side-channel interface options (I2C/UART/SPI/GPIO).
Technical Context
The MAX9295DGTM/VY+ implements a dual-port MIPI CSI-2 receiver with D-PHY v1.2 compliance (80Mbps–2.5Gbps per lane), supporting RAW8/10/12/14/16/20, RGB, and YUV data formats with embedded ECC and checksum error detection. Its GMSL2 physical layer includes adaptive equalization, PRBS-based BER testing, and eye-opening monitoring for continuous link-margin diagnosis on long cables.
In GMSL2 mode, it operates at fixed forward rates of 3Gbps or 6Gbps with 187.5Mbps reverse channel; in GMSL1 mode, it interoperates with legacy 1.5Gbps/3.12Gbps deserializers or achieves up to 4.5Gbps when paired with GMSL2 deserializers configured for GMSL1. All operation is specified across -40°C to +105°C and AEC-Q100 Grade 2 qualified.

Key Features
| Feature | Design Value |
|---|---|
| Dual 4-lane CSI-2 v1.3 input ports | Enables concurrent aggregation of two independent camera sensors (e.g., stereo pair) into one GMSL2 stream without external multiplexing. |
| GMSL2 adaptive equalization | Compensates for >15m coax attenuation and inline connector losses, extending usable cable length beyond standard limits. |
| ASIL-B functional safety architecture | Includes 16-bit CRC on all side-channel traffic and optional 32-bit CRC on video lines, enabling retransmission and watermark-based integrity verification. |
| Programmable spread spectrum | Reduces peak EMI emissions by spreading clock energy across a defined bandwidth - critical for automotive EMC compliance (CISPR 25 Class 5). |
| Crosspoint switch for video pipe remapping | Allows dynamic reordering of CSI-2 virtual channels to match deserializer output sequence - eliminates need for firmware-level video reassembly. |
Applications
| Co-Located Sensors | Stereo Camera |
|---|---|
Use Scenario: Two image sensors mounted on same PCB or housing, sharing power and mechanical alignment. IC Role / Device Role / Timing Role: MAX9295DGTM/VY+ aggregates dual CSI-2 streams into one GMSL2 link while maintaining precise inter-sensor timing via shared reference clock and low-latency control channel. Use Value: Eliminates separate cables and connectors per sensor, reducing harness weight and EMI coupling in compact ADAS modules. | Use Scenario: Left/right camera pair for depth perception in autonomous driving or parking assist. IC Role / Device Role / Timing Role: MAX9295DGTM/VY+ synchronizes capture timing between ports and transmits aligned frames over single coax, preserving sub-frame correlation. Use Value: Enables pixel-accurate stereo matching at 1080p60 using 6Gbps GMSL2 mode, with <1µs inter-port skew. |
| Side Mirror | Radar |
Use Scenario: Camera integrated into vehicle side mirror housing for blind-spot detection.

Use Value: Allows full HD video + bidirectional control over single 50Ω coax, meeting space and thermal constraints inside mirror assemblies. | Use Scenario: Radar signal processor communicating with camera fusion ECU via shared GMSL2 infrastructure. IC Role / Device Role / Timing Role: MAX9295DGTM/VY+ tunnels radar metadata (e.g., object lists, confidence scores) over GMSL2 side channel alongside camera video. Use Value: Enables time-synchronized sensor fusion without adding CAN/FlexRay interfaces - reduces BOM and latency vs. multi-bus architectures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar GMSL2 serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9296ATM/VY+ | Single-port CSI-2 input (4-lane), identical GMSL2 PHY and side-channel features - lacks second CSI-2 port and crosspoint switching. | Suitable only for single-camera links; cannot aggregate dual sensors or support stereo timing synchronization. | Select MAX9296ATM/VY+ when system uses one camera and requires footprint/thermal reduction. |
| MAX96705GTJ/V+ | GMSL2 serializer with single 4-lane CSI-2 input, lower max forward rate (3Gbps only), no GMSL1 compatibility, and no ASIL-B certification. | Targeted at non-safety-critical camera links; lacks reverse-link bandwidth for complex peripheral tunneling. | Choose MAX96705GTJ/V+ for cost-sensitive, non-automotive applications where GMSL1 fallback and ASIL-B are unnecessary. |
Compared with MAX9296ATM/VY+, the MAX9295DGTM/VY+ adds dual-port aggregation and crosspoint remapping essential for stereo vision; versus MAX96705GTJ/V+, it provides GMSL1 interoperability, ASIL-B compliance, and higher 6Gbps forward bandwidth for future-proof 4K sensor support.
