MAX9275GTN/V+

Overview

The MAX9275GTN/V+ is a Gigabit Multimedia Serial Link (GMSL) serializer manufactured by Analog Devices. It converts parallel LVCMOS inputs into a CML serial output with a maximum data rate of 3.12Gbps. The device supports both 50Ω coaxial and 100Ω shielded twisted pair (STP) cable drives, featuring programmable output amplitudes ranging from 100mV to 500mV for single-ended or 100mV to 400mV differential configurations. It operates on a core supply voltage of 1.7V to 1.9V and an I/O supply of 1.7V to 3.6V. The component is housed in a lead-free 56-pin TQFN package measuring 8mm x 8mm with an exposed pad.

Feature Summary

• Supports high-bandwidth mode enabling 1920x720p/60Hz display with 24-bit color at up to 104MHz pixel clock
• Features programmable pre-emphasis and de-emphasis drivers to extend cable reach up to 15 meters at full speed
• Includes embedded control channel supporting UART-UART, UART-I2C, and I2C-I2C modes for remote register programming
• Provides built-in PRBS generator for bit error rate testing and dedicated GPO for touch-screen interrupt handling

Applications

• High-Resolution Automotive Navigation Systems
• Rear-Seat Infotainment Displays
• Megapixel Camera Systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with existing deserializer components in the system design. Confirm that the required ESD protection levels meet ISO 10605 standards for the intended application environment.

Selection Notes

Select this serializer when interfacing parallel video sources with GMSL-compatible deserializers over coaxial or STP cables. Consider the MAX9279 variant if HDCP content protection is required, as it shares identical electrical characteristics. Evaluate the need for spread spectrum modulation to minimize electromagnetic interference in dense electronic environments.

Part Context

This component belongs to the MAX9275/MAX9279 family of GMSL serializers designed for automotive and industrial multimedia applications. It pairs with various GMSL deserializers capable of accepting coax or STP inputs. The series supports backward compatibility with earlier GMSL generations when configured for STP output.

Replacement Considerations

The MAX9279 serves as a functional substitute within the same family, offering identical performance with added HDCP content protection capabilities.
