MAX9275GTN/V+T

Overview

The MAX9275GTN/V+T is a 3.12Gbps Gigabit Multimedia Serial Link (GMSL) serializer featuring parallel LVCMOS inputs and a CML serial output. It supports programmable drive for 50Ω coax or 100Ω shielded twisted pair cables, with output amplitudes adjustable from 100mV to 500mV single-ended or 100mV to 400mV differential. The device operates with core supplies of 1.7V to 1.9V and I/O supplies of 1.7V to 3.6V. It accommodates pixel clocks up to 104MHz and audio sample rates up to 192kHz with 32-bit depth. The component includes an embedded control channel operating at speeds up to 1Mbps and meets automotive temperature ranges of -40°C to +105°C.

• Rear-seat infotainment systems
• Megapixel camera systems in vehicles

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the component matches the required voltage levels and interface configurations for your design. Cross-reference the part number with authorized distributors to confirm authenticity and availability status before finalizing procurement decisions.

Selection Notes

Select this serializer when interfacing parallel LVCMOS sources to GMSL deserializers via coaxial or STP cabling. Consider the MAX9279 variant if HDCP content protection is required, as it shares identical electrical characteristics. Evaluate cable length requirements to determine necessary pre/emphasis settings and verify compatibility with the target deserializer's input impedance and signaling mode.

Part Context

This component belongs to the Maxim Integrated GMSL family of serializers designed for automotive and industrial applications. It pairs specifically with GMSL-compatible deserializers to transmit high-speed video and audio data over long distances. The GTN/V+T designation indicates a lead-free TQFN package version suitable for surface-mount assembly in compact electronic designs.

Replacement Considerations

The MAX9279 serves as a functional equivalent with added HDCP support. Verify pinout and register compatibility when substituting within existing GMSL link architectures. Ensure that any replacement maintains the same serial bit rate capabilities and power supply requirements to preserve system integrity.
