MAX9218ECM/V+T

Serializers, Deserializers Overview

The MAX9218ECM/V+T is a digital video serializer/deserializer component manufactured by Analog Devices Inc./Maxim Integrated. It functions as a DC-balanced LVDS deserializer designed for high-speed video transmission systems. The device operates with a parallel clock frequency ranging from 7MHz to 35MHz, supporting a maximum serial data rate of 700Mbps. It accepts a single LVDS differential input and provides 27 parallel outputs, comprising 18 bits of RGB video data and 9 bits of control data. The unit utilizes a +3.3V core supply voltage and supports an output supply voltage range of 1.7V to 3.6V to interface with various logic levels. It is housed in a 48-lead LQFP package and is qualified for automotive applications under the AEC-Q100 standard.

Serializers, Deserializers Feature Summary

• Proprietary data decoding mechanism ensures DC balance and reduces electromagnetic interference (EMI).
• Control data is deserialized during video blanking periods to optimize bandwidth usage.
• Features five control data inputs that provide single-bit-error tolerance through majority voting.
• Output transition times are scaled to operating frequency to further minimize EMI.

Serializers, Deserializers Applications

• Navigation System Display
• In-Vehicle Entertainment System
• Video Camera
• LCD Displays

Serializers, Deserializers Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. The 'ECM' designation indicates a 48-lead LQFP package suitable for industrial or automotive environments. The '/V+' suffix denotes automotive qualification compliant with AEC-Q100 standards. Ensure compatibility with existing PCB footprints for the LQFP-48 form factor before procurement.

Serializers, Deserializers Selection Notes

Select this component when a robust, DC-balanced LVDS deserializer is required for automotive video links. It pairs specifically with the MAX9217 serializer to form a complete transmission system. Consider the separate VCCO supply pin if interfacing with 1.8V logic devices. Verify that the application requires the 7MHz to 35MHz parallel clock frequency range supported by the RNG0 and RNG1 configuration pins.

Serializers, Deserializers Part Context

This part belongs to the MAX9218 family of serializers and deserializers developed by Maxim Integrated, now part of Analog Devices. It is engineered for digital video transmission over twisted-pair cables. The device is often used in conjunction with the MAX9217 serializer to create a synchronized, low-EMI video link suitable for demanding automotive and industrial display applications.

Serializers, Deserializers Replacement Considerations

The MAX9218ETM+ serves as a functional alternative within the same family, offering identical electrical performance but utilizing a 48-lead Thin QFN-EP package instead of the LQFP form factor. Designers must evaluate mechanical footprint differences and thermal dissipation requirements when considering this substitution.
