MAX9291GTN/VY+

Serializers, Deserializers Overview

The MAX9291GTN/VY+ is a GMSL serializer designed to convert HDMI inputs into Gigabit Multimedia Serial Link outputs for transmission over coaxial or shielded twisted-pair 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 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 core supply voltage ranges from 1.8V to 3.3V, while the I/O supply operates between 1.7V and 3.6V. It is housed in a 56-pin, 8mm x 8mm TQFN package.

Serializers, Deserializers Feature Summary

• Supports programmable output amplitudes for both single-ended and differential signaling
• Includes embedded control channel for register programming independent of video timing
• Features built-in PRBS generator for serial link BER testing

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure storage conditions meet moisture sensitivity level specifications prior to assembly. Validate that the ordering suffix matches the required tape and reel configuration for automated placement processes.

Serializers, Deserializers Selection Notes

Select this serializer when HDMI source integration with GMSL deserializers is required. Consider the MAX9293 variant if HDCP content protection is necessary for the application. Ensure the downstream deserializer supports the selected cable type, whether 50Ω coaxial or 100Ω STP. Verify that the system power supplies align with the specified core and I/O voltage ranges.

Serializers, Deserializers Part Context

This component belongs to the MAX9291/MAX9293 family of 3.12Gbps GMSL serializers. These devices are engineered for high-bandwidth video transmission in demanding environments. The series provides backward compatibility with existing GMSL infrastructure while offering enhanced features like spread spectrum modulation to reduce electromagnetic interference.

Serializers, Deserializers Replacement Considerations

The MAX9293 serves as a functional alternative within the same family, distinguished by integrated HDCP support. Direct pin-to-pin substitution requires verifying HDCP implementation needs. Other GMSL serializers may require significant circuit redesign due to differing interface protocols and pin configurations.
