MAX9291GTN+T

Serializers, Deserializers Overview

The MAX9291GTN+T is a GMSL serializer that converts HDMI inputs to Gigabit Multimedia Serial Link outputs for transmission over coax or STP cables. It supports serial bit rates up to 3.12Gbps and pixel clocks from 25MHz to 104MHz. The device features an HDMI 1.4a input with integrated equalizer, DDC, and termination. Audio support includes L-PCM I2S stereo and up to eight channels of L-PCM in TDM mode, with sample rates from 32kHz to 192kHz and depths up to 32 bits. The core supply ranges from 1.8V to 3.3V, while the I/O supply ranges from 1.7V to 3.6V. It is housed in a 56-pin, 8mm x 8mm TQFN package.

Serializers, Deserializers Feature Summary

• Converts HDMI signals to GMSL output for long-distance transmission
• Supports high-bandwidth modes for 1920x720p/60Hz displays
• Includes programmable pre/deemphasis and spread spectrum capabilities
• Provides embedded control channel for register programming

Serializers, Deserializers Applications

• High-resolution automotive navigation systems
• Rear-seat infotainment terminals
• Megapixel camera systems

Serializers, Deserializers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm current production status directly with Analog Devices as availability may vary. Ensure HDMI licensing requirements are met prior to implementation.

Serializers, Deserializers Selection Notes

Select this component when HDMI input conversion to GMSL is required for video and audio transmission. Consider the MAX9293 variant if HDCP content protection is necessary, as it shares identical functionality otherwise. Verify cable length requirements to determine if programmable pre-emphasis settings are sufficient.

Serializers, Deserializers Part Context

This part belongs to the MAX9291/MAX9293 family of serializers designed for GMSL applications. It pairs with compatible GMSL deserializers to form a complete link. The device is distinct from the MAX9293 primarily by the absence of built-in HDCP management capabilities.

Serializers, Deserializers Replacement Considerations

The MAX9293 serves as a functional substitute with added HDCP support. Other MAX9291 variants with different suffixes may offer alternative packaging or temperature ratings.
