MAX9259GTN/V+

Serializers, Deserializers Overview

The MAX9259GTN/V+ is a serializer for the Gigabit Multimedia Serial Link (GMSL) family, designed to transmit high-speed video, audio, and control data over shielded twisted-pair cables. It operates at serial bit rates up to 3.125Gbps, supporting display resolutions from QVGA to XGA or dual-view WVGA with 18- or 24-bit color depth. The device accepts parallel CMOS inputs including I2S audio data up to 192kHz sample rate and 32 bits per sample. It features a full-duplex differential control channel operating between 100kbps and 1Mbps. Power supplies include DVDD/AVDD ranging from 1.7V to 1.9V and IOVDD from 1.7V to 3.6V. The component is housed in a 56-pin TQFN package with an exposed pad.

Serializers, Deserializers Feature Summary

• Supports preemphasis and channel equalization to extend link length and enhance reliability
• Includes programmable spread spectrum functionality to reduce electromagnetic interference
• Integrates a built-in PRBS BER tester for serial link verification
• Provides ESD protection compliant with ISO 10605 and IEC 61000-4-2 standards

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify that the ordering suffix 'T' indicates tape-and-reel packaging rather than bulk units. Confirm the '/V+' designation ensures compliance with AEC-Q100 automotive qualification standards and lead-free RoHS requirements. Cross-reference the specific pinout for the 56-pin TQFN variant against the target PCB layout to ensure correct alignment of the exposed thermal pad.

Serializers, Deserializers Selection Notes

Select this serializer when paired with the MAX9260 deserializer for GMSL applications requiring up to 3.12Gbps transmission speeds. Ensure the system design accommodates the required 1.8V analog/digital core supplies and 1.8V to 3.3V I/O voltage levels. Verify that the host microcontroller can interface with the integrated UART/I2C control channels for peripheral management across the serial link.

Serializers, Deserializers Part Context

This component belongs to the Maxim Integrated GMSL series, functioning as the transmitter side of a dedicated multimedia serial link. It is specifically engineered to replace traditional parallel LVDS connections in automotive environments, reducing cable weight and complexity while maintaining high bandwidth for video and synchronized audio streams.

Serializers, Deserializers Replacement Considerations

Direct functional replacements within the same GMSL family include the MAX9259GCB/V+T (64-pin TQFP). Designers must account for package dimension differences and verify pin compatibility before substituting the 56-pin TQFN version with the 64-pin TQFP variant.
