MAX9291GTN/V+

Serializers, Deserializers Overview

The MAX9291GTN/V+ is a GMSL serializer that converts HDMI inputs to serial outputs for transmission over coax or STP cables. It supports up to 3.12Gbps data rates and 104MHz pixel clocks. The device accepts HDMI 1.4a inputs with integrated equalization and DDC. Audio capabilities include L-PCM I2S stereo and up to eight channels of L-PCM in TDM mode, supporting sample rates from 32kHz to 192kHz with depths up to 32 bits. The embedded control channel operates at 9.6kbps to 1Mbps. Power supplies are 1.8V to 3.3V for the core and 1.7V to 3.6V for I/O. It is housed in a 56-pin, 8mm x 8mm TQFN package.

Serializers, Deserializers Feature Summary

• Converts HDMI video and audio signals into high-speed serial links for long-distance transmission
• Supports flexible control channel configurations including UART-to-UART and I2C modes
• Includes programmable pre-emphasis and spread spectrum features to reduce EMI
• Provides dedicated general-purpose output for remote interrupt handling

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm HDMI licensing status as required by the manufacturer. Check current production status through authorized distributors, as availability may vary. Ensure supply voltage requirements match system design constraints before finalizing procurement.

Serializers, Deserializers Selection Notes

Select this component when HDMI input conversion to GMSL is required for automotive or industrial applications. Consider the MAX9293 if HDCP content protection is necessary, as it shares identical functionality otherwise. Evaluate cable length requirements to determine if programmable pre-emphasis settings are needed for signal integrity over longer distances.

Serializers, Deserializers Part Context

This part belongs to the MAX9291/MAX9293 family of 3.12Gbps GMSL serializers manufactured by Analog Devices Inc./Maxim Integrated. These devices are designed to pair with GMSL deserializers for complete multimedia link solutions. The series addresses the need for reliable, high-bandwidth video transmission in environments where traditional parallel interfaces are impractical due to size and interference constraints.

Serializers, Deserializers Replacement Considerations

The MAX9293 serves as a functional substitute with added HDCP support. Other members of the MAX929x family may offer similar serialization but require verification of pin compatibility and feature sets.
