Product details
Overview
MAX9295DGTM/VY+T from Analog Devices is a GMSL2 dual CSI-2 serializer with GMSL1 backward compatibility, converting up to two 4-lane MIPI CSI-2 v1.3 inputs (80Mbps–2.5Gbps/lane) into a single-wire GMSL2 forward link (3/6Gbps) and reverse control channel (187.5Mbps) for automotive camera links over coax or STP cables up to 20m. It supports RAW8/10/12/14/16/20, RGB888, and YUV formats, includes ASIL-B functional safety features, and operates across -40°C to +105°C.
For engineers reviewing the MAX9295DGTM/VY+T datasheet, MAX9295DGTM/VY+T pinout, MAX9295DGTM/VY+T application, or MAX9295DGTM/VY+T equivalent, this device is selected for high-reliability automotive vision systems requiring long-cable video transport, concurrent side-channel I2C/UART/SPI/GPIO, and GMSL2–GMSL1 interoperability in stereo camera, radar, lidar, and side-mirror modules.
Technical Context
The MAX9295DGTM/VY+T implements a dual-port MIPI CSI-2 receiver with D-PHY v1.2 compliance, supporting lane reassignment, polarity flip, and ECC/checksum error detection per port. Its GMSL2 physical layer delivers fixed-rate 3Gbps or 6Gbps forward transmission with adaptive equalization and eye-opening monitoring for >15m coax cable operation.
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. Side-channel support includes primary/pass-through I2C/UART, SPI, register-programmable GPIO, and 16-bit CRC protection for all side-channel data.

FAQ
What is the maximum supported cable length for MAX9295DGTM/VY+T at 6Gbps forward rate?
The MAX9295DGTM/VY+T supports up to 15m over 50Ω foam-dielectric coax, 9m over 50Ω solid-dielectric coax, and 8m over 100Ω AWG26 shielded twisted pair at 6Gbps forward rate and +105°C ambient temperature, as verified in Table 1 of the official datasheet. These lengths assume worst-case aging and attenuation conditions.
Does MAX9295DGTM/VY+T support MIPI CSI-2 virtual channels?
Yes, the MAX9295DGTM/VY+T supports 4-channel CSI-2 virtual-channel functionality, allowing multiple logical data streams (e.g., separate YUV and metadata channels) to be multiplexed over a single physical CSI-2 port-enabling efficient bandwidth utilization in multi-sensor or multi-format camera systems.
How does the MAX9295DGTM/VY+T implement functional safety for ASIL-B compliance?
The MAX9295DGTM/VY+T achieves ASIL-B compliance through 16-bit CRC protection on all side-channel data (I2C/UART/SPI/GPIO), optional 32-bit CRC on video-line data, and video watermark insertion/detection for frame-level integrity verification-features explicitly documented in the "ASIL-Relevant Functional Safety Features" section of its datasheet.
Can MAX9295DGTM/VY+T operate with both coaxial and shielded twisted pair cables?
Yes, the MAX9295DGTM/VY+T is designed for interoperability with both 50Ω coaxial cables (foam or solid dielectric) and 100Ω shielded twisted pair (AWG26), with distinct maximum length specifications per cable type and data rate-validated across the full -40°C to +105°C automotive temperature range.
What package variant does MAX9295DGTM/VY+T use, and why is it significant for automotive applications?
MAX9295DGTM/VY+T uses the 48-pin TQFN-SW (Side-Wettable) package (package code T4877Y), which features wettable flanks enabling automated optical inspection (AOI) of solder joints-a critical requirement for zero-defect manufacturing in automotive electronics assembly lines.
