Product details
Overview
MAX96708GTJ+ from Maxim Integrated is a 14-bit GMSL deserializer for automotive camera links, supporting up to 1.74Gbps serial-bit rate over coax or STP cable. It features adaptive equalization (enabling 15m cable reach at full speed), embedded UART/I2C control channel (9.6kbps–1Mbps), and crosspoint switch for flexible video data routing. Designed for AEC-Q100 Grade 2 (−40°C to +115°C), it serves as the parallel video interface endpoint in safety-critical ADAS camera systems.
For engineers reviewing the MAX96708GTJ+ datasheet, MAX96708GTJ+ pinout, MAX96708GTJ+ application, or MAX96708GTJ+ equivalent, key selection criteria include spread-spectrum input tracking capability, ESD robustness (±8kV contact/±15kV air), dual-supply operation (1.7V–1.9V core / 1.7V–3.6V I/O), and hardware-selectable I²C addresses (15 options).
Technical Context
The MAX96708GTJ+ implements a GMSL (Gigabit Multimedia Serial Link) deserialization architecture with spread-spectrum clock tracking, enabling high-EMI-tolerance reception from remote serializers like MAX96709. Its adaptive line equalizer dynamically compensates for cable loss across temperature and length variations.
It integrates a bidirectional control channel supporting UART, I²C (with clock stretch), and UART-to-I²C translation modes-allowing host-side configuration of both serializer and camera registers independent of video timing. The 32-pin TQFN package hosts dedicated GPI/GPO pins for frame sync triggering and error signaling (ERRB output).

FAQ
What is the maximum supported cable length for MAX96708GTJ+ at full 1.74Gbps data rate?
The MAX96708GTJ+ supports up to 15 meters of standard 50Ω coaxial cable at its maximum 1.74Gbps serial bit rate, enabled by its adaptive equalization circuitry that dynamically compensates for frequency-dependent attenuation. This performance is validated per manufacturer specifications and applies to typical automotive-grade RG-174 or equivalent cables under AEC-Q100 operating conditions. Cable length may vary with impedance mismatch or environmental noise.
Does MAX96708GTJ+ support both UART and I²C control protocols simultaneously?
Yes, the MAX96708GTJ+ supports UART, I²C (with clock stretch), and mixed UART/I²C modes on its embedded control channel-but not simultaneously on the same physical interface. Mode selection is configured via register settings (e.g., MAIN_CONFIG register). In UART-to-I²C mode, the deserializer translates incoming UART commands into I²C transactions directed to the serializer or camera, enabling unified host-side control across heterogeneous devices.
How does the crosspoint switch in MAX96708GTJ+ improve system design flexibility?
The crosspoint switch in MAX96708GTJ+ allows programmable mapping of serialized input data lanes to any parallel output lane (e.g., DATA[11:0]), decoupling physical cable connections from logical video routing. This enables dynamic reassignment of camera sources to display pipelines or memory buffers without hardware changes-critical for multi-camera architectures like surround-view systems where camera roles may shift based on vehicle state or software-defined use cases.
What is the purpose of the ERRB pin on MAX96708GTJ+?
The ERRB pin on MAX96708GTJ+ is an open-drain, active-low output that asserts when video data corruption or control-channel communication errors are detected-including CRC failures, lock-loss events, or invalid packet structures. It provides immediate hardware-level fault signaling to the host processor or safety monitor, enabling rapid fail-safe responses such as display blanking or camera reinitialization-essential for ASIL-B compliant ADAS implementations.
Can MAX96708GTJ+ operate with different core and I/O supply voltages?
Yes, MAX96708GTJ+ supports independent supply domains: VCC_CORE accepts 1.7V–1.9V for internal logic and SERDES, while VCC_IO accepts 1.7V–3.6V for parallel video outputs and control interfaces. This dual-supply architecture allows direct interfacing with 1.8V FPGAs, 3.3V microcontrollers, or mixed-voltage SoCs without level-shifting components-reducing BOM cost and PCB area in space-constrained automotive modules.
