Overview
MAX9272GTM+ from Maxim Integrated is a 28-bit GMSL deserializer designed for automotive camera links over 50Ω coax or 100Ω STP cable, supporting up to 1.5Gbps serial bit rate, 6.25–100MHz pixel clock, and dual-rate parallel output. It pairs with MAX9271/MAX9273 serializers and operates from -40°C to +105°C in automotive camera systems.
For engineers reviewing the MAX9272GTM+ datasheet, MAX9272GTM+ pinout, MAX9272GTM+ application, or MAX9272GTM+ equivalent, key selection factors include its embedded UART/I²C control channel (9.6kbps–1Mbps), programmable equalizer for 15m full-speed cable support, PRBS BER testing capability, dual GPIOs for backlight control, and compliance with ISO 10605 (±30kV air) and IEC 61000-4-2 (±15kV air) ESD standards.
Technical Context
The MAX9272GTM+ implements a GMSL-compliant serial link receiver with adaptive line equalization, supporting both single- and double-output parallel modes synchronized to pixel clock. Its reverse control channel operates bidirectionally at up to 1Mbps in UART-to-UART or UART-to-I²C mode with clock stretch capability.
It integrates error detection via CRC and Hamming code, HV/VS tracking for frame sync, and staggered parallel output timing to reduce EMI. The device features three-level configuration inputs (CX/TP), local control-channel enable (LCCEN), and programmable spread spectrum on parallel outputs with automatic tracking of incoming spread spectrum on serial input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Serial Bit Rate | Up to 1.5Gbps - supports megapixel camera video streams over coax/STP without compression. |

FAQ
What is the maximum supported cable length for MAX9272GTM+ at full 1.5Gbps data rate?
The MAX9272GTM+ supports up to 15 meters of standard 50Ω coax cable at full 1.5Gbps serial bit rate, enabled by its programmable line equalizer that compensates for frequency-dependent attenuation. Performance depends on cable quality and connector insertion loss; verified using FAKRA-compatible coax assemblies per Table 15 in the MAX9272GTM+ datasheet.
Does MAX9272GTM+ support both coaxial and shielded twisted-pair (STP) cables?
Yes, the MAX9272GTM+ natively supports both 50Ω coax and 100Ω STP cables. Cable type is selected via the three-level CX/TP input pin, which configures internal termination, equalization, and signal detection thresholds accordingly. This eliminates manual hardware changes when migrating between cable architectures.
How does the embedded control channel of MAX9272GTM+ operate during active video transmission?
The MAX9272GTM+ control channel operates asynchronously and independently of video timing, supporting UART-to-UART, UART-to-I²C, or I²C-to-I²C modes at 9.6kbps–1Mbps. It uses time-division multiplexing with the serial video stream, allowing continuous register read/write access-including sensor configuration and diagnostics-without interrupting video flow.
Can MAX9272GTM+ generate frame sync signals for camera synchronization?
Yes, the MAX9272GTM+ provides frame sync capability via its dedicated GPI input configured for "up/down" edge detection, and supports HV/VS encoding and tracking to reconstruct horizontal/vertical sync timing from the serialized stream. This enables precise frame alignment in multi-camera systems without external sync generators.
What power supply requirements must be met for reliable operation of MAX9272GTM+?
The MAX9272GTM+ requires three independent supplies: AVDD/DVDD = 1.7V–1.9V (core), IOVDD = 1.7V–3.6V (I/O), with tight decoupling per Figure 43 in the datasheet. Core supplies must deliver ≤90mA max current; IOVDD must support open-drain GPIO loads. Exposed pad must be soldered to solid PCB ground plane for thermal and EMI performance.
