MAX9279GTN+

Serializers, Deserializers Overview

The MAX9279GTN+ is a Gigabit Multimedia Serial Link (GMSL) serializer manufactured by Analog Devices Inc. It converts parallel LVCMOS inputs into a CML serial output, supporting data rates up to 3.12Gbps. The device features programmable drive for 50Ω coax or 100Ω shielded twisted pair (STP) cables, with output amplitudes adjustable from 100mV to 500mV single-ended or 100mV to 400mV differential. It includes HDCP content protection and supports audio channels with sample rates up to 192kHz and depths up to 32 bits. Operating temperatures range from -40°C to +105°C within a 56-pin TQFN package.

Serializers, Deserializers Feature Summary

• Integrated HDCP content protection for secure video transmission
• Programmable pre-emphasis and spread spectrum to reduce EMI
• Supports high-immunity reverse control channel modes
• Built-in PRBS generator for link verification

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm that the component meets AEC-Q100 automotive qualification standards if required for the target application. Ensure compatibility with GMSL deserializers capable of handling the selected cable impedance.

Serializers, Deserializers Selection Notes

Select this serializer when HDCP encryption is mandatory for the video link. Choose between coax or STP configurations based on cable infrastructure constraints. Verify that the parallel input clock frequency aligns with the desired serial bit rate and bandwidth settings. Ensure power supply rails match the specified core and I/O voltage ranges.

Serializers, Deserializers Part Context

This component belongs to the MAX9275/MAX9279 family of GMSL serializers. The MAX9279 variant specifically adds HDCP support compared to the MAX9275. Both devices share identical electrical characteristics and pinouts, differing primarily in the inclusion of encryption protocols within the MAX9279 architecture.

Serializers, Deserializers Replacement Considerations

The MAX9275GTN+ serves as a functional substitute if HDCP encryption is not required. Verify that any replacement maintains the same TQFN-EP-56 package dimensions and thermal characteristics to ensure mechanical compatibility.
