MAX9291GTN/V+T

Serializers, Deserializers Overview

The MAX9291GTN/V+T is a GMSL serializer that converts HDMI inputs to serial outputs for transmission over coax or STP cables up to 15m. It supports a serial bit rate of 3.12Gbps and pixel clocks from 25MHz to 104MHz. The device accepts HDMI 1.4a inputs with integrated equalization and DDC. Audio channels support L-PCM I2S stereo and up to eight TDM channels, with sample rates from 32kHz to 192kHz and depths up to 32 bits. Control channels operate at 9.6kbps to 1Mbps in UART or I2C modes. Core supply ranges from 1.8V to 3.3V, while 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

• Embedded control channel supporting UART and I2C protocols
• Built-in PRBS generator for link verification

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 tape-and-reel configuration. Ensure compatibility with system power supplies and interface requirements before procurement. Confirm availability status directly with authorized distributors as production status may vary.

Serializers, Deserializers Selection Notes

Select this component when an HDMI source requires conversion to a GMSL serial link for long-distance transmission. Consider the MAX9293 if HDCP content protection is required, as it shares identical functionality otherwise. Ensure the paired deserializer supports the selected output impedance (coax or STP).

Serializers, Deserializers Part Context

This part belongs to the MAX9291/MAX9293 family of Gigabit Multimedia Serial Link serializers. These devices are designed to pair with compatible GMSL deserializers to form high-speed video links. The GTN/V+T suffix indicates a specific thermal and packaging variant within the Maxim Integrated product line.

Serializers, Deserializers Replacement Considerations

The MAX9293 serves as a functional equivalent with added HDCP support. Other GMSL serializers like the MAX9275 offer similar serialization but differ in input types and pin configurations. Verify register compatibility and electrical characteristics when substituting.
