Product details
Overview
MAX96705GTJ+T from Maxim Integrated is a 16-bit GMSL serializer designed for automotive camera links, supporting up to 1.74Gbps serial-bit rate, 116MHz parallel clock (12-bit HDR), and high-immunity control-channel operation at 9.6kbps–1Mbps in UART/I²C/mixed modes. It drives 50Ω coax or 100Ω STP cables up to 15m with programmable pre/deemphasis and meets AEC-Q100 Grade 2 (-40°C to +115°C).
For engineers reviewing the MAX96705GTJ+T datasheet, MAX96705GTJ+T pinout, MAX96705GTJ+T application, or MAX96705GTJ+T equivalent, key selection criteria include GMSL compliance, coax/STP cable drive capability, error-detecting/retransmitting control channel, spread-spectrum EMI reduction, and integrated PRBS generator for BER testing.
Technical Context
The MAX96705GTJ+T implements a GMSL-compliant serial link with forward video/control data transmission and reverse control-channel feedback. Its crosspoint switch accepts arbitrary input bitmap mapping, and its video timing generator supports encoded HSYNC/VSYNC modes for flexible synchronization.
Control-channel operation supports UART, I²C (with clock stretch), and UART-to-I²C conversion-enabling independent register programming of serializer, deserializer, and camera without video timing dependency. Error detection triggers automatic packet retransmission, and high-immunity mode enhances EMC tolerance in noisy automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMSL serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX96706GTJ+T | Pin-compatible variant with extended 12.5–125MHz PCLK support and added 24-bit mode; higher max serial bit rate (1.87Gbps). | Required for >116MHz parallel clocks or 24-bit sensor interfaces; otherwise functionally identical in standard GMSL links. | Select MAX96706GTJ+T only when higher bandwidth or 24-bit depth is needed; MAX96705GTJ+T remains optimal for cost-sensitive 12-bit HDR systems. |
| TI DS90UB953TRGZT | FSA-based serializer with FPD-Link III compatibility; different control protocol (I²C-only, no UART); no built-in PRBS generator. | Used in non-GMSL ecosystems (e.g., TI TDAx SoCs); requires separate ESD protection and lacks high-immunity control channel. | Choose DS90UB953TRGZT only when interfacing with FPD-Link III deserializers or TI-specific platforms; not drop-in compatible with GMSL infrastructure. |
Compared with MAX96706GTJ+T and DS90UB953TRGZT, the MAX96705GTJ+T delivers best-in-class supply current (93mA max), native GMSL compliance, and integrated high-immunity control-making it the preferred choice for automotive safety camera systems requiring AEC-Q100 qualification and coax cable simplicity.

FAQ
What is the maximum cable length supported by MAX96705GTJ+T?
The MAX96705GTJ+T supports up to 15m of standard 50Ω coaxial cable at full speed (1.74Gbps) when programmable pre/deemphasis is enabled. This capability is verified per Maxim's datasheet AC characteristics and confirmed in typical application circuits using industry-standard RG-174 or equivalent coax. Cable length may vary based on quality, shielding, and connector losses.
Does MAX96705GTJ+T support both UART and I²C control interfaces simultaneously?
Yes, the MAX96705GTJ+T supports UART, I²C (with clock stretch), and UART-to-I²C conversion modes on shared RX/SDA and TX/SCL pins. The mode is selected via register configuration-not hardware pins-allowing dynamic switching during operation without changing PCB layout or external pull-ups.
Is MAX96705GTJ+T pin-compatible with MAX9271?
Yes, the MAX96705GTJ+T is explicitly stated as function- and pin-compatible with the MAX9271 in Maxim's official datasheet General Description. Both use identical 32-pin TQFN packages, matching pin assignments for power, I/O, timing, and serial outputs-enabling direct replacement in existing MAX9271 designs.
What is the purpose of the GPO pin on MAX96705GTJ+T?
The GPO (General-Purpose Output) pin on MAX96705GTJ+T provides a programmable digital output used primarily for camera frame-sync triggering. It can be configured to assert on rising/falling edges of HS, VS, or DE signals, enabling precise synchronization between image capture and external illumination or processing units in safety-critical ADAS applications.
How does the error detection and retransmission feature work in MAX96705GTJ+T?
The MAX96705GTJ+T implements CRC-based error detection on all control-channel packets. When an error is detected in received data, the device automatically requests retransmission from the source-ensuring reliable register programming of remote sensors or deserializers without software intervention or video stream disruption.
