MAX9281GTM/V+T

Serializers, Deserializers Overview

The MAX9281GTM/V+T is a Gigabit Multimedia Serial Link (GMSL) serializer manufactured by Analog Devices Inc./Maxim Integrated. It features three or four LVDS data lane inputs and a CML serial output programmable for 50Ω coaxial or 100Ω shielded twisted pair (STP) cable drive. The device supports a maximum serial bit rate of 3.12Gbps with pixel clock frequencies ranging from 6.25MHz to 104MHz. It integrates High-Bandwidth Digital Content Protection (HDCP) and an embedded control channel operating at up to 1Mbps in UART or I2C modes. Power supplies include a core voltage of 1.7V to 1.9V and an I/O voltage of 1.7V to 3.6V, housed in a 48-pin TQFN package.

Serializers, Deserializers Feature Summary

• Supports HDCP content protection for secure video transmission
• Features programmable pre-emphasis and spread spectrum to reduce EMI
• Includes a high-immunity reverse control channel for noise rejection
• Provides built-in PRBS generator for link verification

Serializers, Deserializers Applications

• High-Resolution Automotive Navigation
• Rear-Seat Infotainment Systems
• Megapixel Camera Systems

Serializers, Deserializers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm that the component meets AEC-Q100 automotive qualification standards if required for the target application environment. Ensure compatibility with existing GMSL deserializers before finalizing procurement.

Serializers, Deserializers Selection Notes

Select this serializer when HDCP compliance is mandatory for the video link. Choose this model over the MAX9277 specifically for its integrated content protection capabilities. Verify that the system design accommodates the required power supply rails and that the chosen cable medium matches the programmed output drive settings.

Serializers, Deserializers Part Context

This component belongs to the MAX9277/MAX9281 family of GMSL serializers. While functionally identical to the MAX9277 regarding video serialization, the MAX9281 variant uniquely incorporates HDCP encryption logic. It pairs with compatible GMSL deserializers to form a complete point-to-point multimedia link.

Serializers, Deserializers Replacement Considerations

The MAX9277AGTM/V+T serves as a functional substitute if HDCP support is not required. Verify that the replacement part number aligns with the desired packaging configuration and that the absence of HDCP does not violate system security requirements.
