MAX9277GTM/V+

Overview

The MAX9277GTN/V+ is a Gigabit Multimedia Serial Link (GMSL) serializer manufactured by Analog Devices Inc./Maxim Integrated. It supports data rates up to 3.12Gbps and features three or four LVDS input lanes with a CML serial output. The device accommodates both 50Ω coaxial and 100Ω shielded twisted pair (STP) cable drives, with programmable output amplitudes ranging from 100mV to 500mV single-ended or 100mV to 400mV differential. It operates on a core supply of 1.7V to 1.9V and an I/O supply of 1.7V to 3.6V. The component is housed in a lead-free 48-pin, 7mm x 7mm TQFN package with an exposed pad.

Feature Summary

• Supports high-definition video applications with up to 104MHz high-bandwidth mode for 1920x720p/60Hz displays.
• Features programmable pre/deemphasis drivers to extend cable reach and spread spectrum modulation to reduce EMI.
• Includes an embedded control channel supporting UART and I2C modes for remote register programming.
• Provides dedicated GPO outputs for touch-screen interrupt requests and system verification.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm AEC-Q100 qualification status if automotive compliance is required. Ensure compatibility with paired deserializers for coax or STP configurations before procurement.

Selection Notes

Select this serializer when interfacing LVDS camera sources to GMSL deserializers over long-distance cables. Consider the MAX9281 variant if HDCP content protection is necessary. Verify that the target application requires the specific 48-pin TQFN footprint and thermal characteristics provided by this package.

Part Context

This component belongs to the MAX9277/MAX9281 family of GMSL serializers designed for automotive and industrial multimedia links. It pairs with compatible GMSL deserializers to transmit high-speed video and audio data. The MAX9281 is functionally identical but includes integrated HDCP support.

Replacement Considerations

The MAX9281 is a direct functional replacement within the same family, distinguished primarily by its inclusion of HDCP content protection capabilities. Other series members may offer different pin counts or lane configurations.

FAQ

What types of cables can the MAX9277 drive?

The serializer output is programmable to drive either 50Ω coaxial cables or 100Ω shielded twisted pair (STP) cables.

Does the MAX9277 support HDCP?

No, the MAX9277 does not include HDCP content protection. The MAX9281 is the variant in this family that provides HDCP support.

What is the maximum pixel clock frequency supported?

The device supports a pixel clock frequency ranging from 6.25MHz to 104MHz, depending on the bandwidth setting.
