MAX9278AGTM+

Serializers, Deserializers Overview

The MAX9278AGTM+ is a GMSL deserializer that receives data from a GMSL serializer over 50Ω coax or 100Ω STP cable and outputs deserialized data on three of four LVDS ports. It supports serial bit rates up to 3.12Gbps with pixel clocks ranging from 6.25MHz to 104MHz. The core supply voltage is 3.0V to 3.6V, while the I/O supply operates between 1.7V and 3.6V. It features an embedded control channel supporting UART-to-UART, UART-to-I2C, and I2C-to-I2C modes at speeds up to 1Mbps. The device includes two GPIO ports, a dedicated GPI for touch-screen interrupts, and programmable equalization for cables up to 15m.

Serializers, Deserializers Feature Summary

• Enables long-distance signal integrity through programmable cable equalization
• Provides flexible audio processing with L-PCM I2S stereo and TDM modes up to 192kHz
• Integrates a bidirectional control channel for independent register programming

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature range. Confirm availability status directly with authorized distributors as stock levels fluctuate. Ensure the component meets AEC-Q100 requirements if used in automotive environments. Cross-reference the manufacturer part number with the datasheet revision history to validate current specifications.

Serializers, Deserializers Selection Notes

Select this model when utilizing coaxial or STP cabling for GMSL applications requiring deserialization. Consider the MAX9282A variant if HDCP content protection is required for the same functionality. Evaluate the need for programmable spread spectrum to manage EMI in sensitive environments. Verify that the system power supplies align with the specified 3.0V to 3.6V core and 1.7V to 3.6V I/O ranges.

Serializers, Deserializers Part Context

This component belongs to the MAX9278A/MAX9282A family of gigabit multimedia serial link deserializers. It is designed to pair with GMSL serializers capable of coax output. The device is manufactured by Analog Devices Inc./Maxim Integrated and is housed in a lead-free 48-pin 7mm x 7mm TQFN/SWTQFN package with an exposed pad.

Serializers, Deserializers Replacement Considerations

The MAX9282A is functionally identical but includes HDCP content protection. Other GMSL deserializers may require different cabling or pin configurations.
