MAX9218ECM/V+

Serializers, Deserializers Overview

The MAX9218ECM/V+ 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 data transmission. The device operates with a parallel clock frequency ranging from 7MHz to 35MHz, supporting a serial data rate of up to 700Mbps. It features one LVDS input and converts the serial stream into 18 bits of parallel video data and 9 bits of control data. The unit utilizes a +3.3V core supply voltage and accepts an output supply voltage between 1.7V and 3.6V. It is housed in a 48-lead LQFP package and supports an operating temperature range from -40°C to +85°C.

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.
• Five control data inputs provide single-bit-error tolerance through majority voting decoding.
• Output transition times are scaled to the operating frequency to further minimize EMI.

Serializers, Deserializers Applications

• Navigation system displays
• In-vehicle entertainment systems
• Video cameras
• LCD displays

Serializers, Deserializers Procurement Notes

Verify the specific suffix /V+ indicates automotive qualification status when sourcing this component. Confirm that the 48-lead LQFP package matches your PCB footprint requirements. Ensure the design accommodates the separate power domains for VCC, VCCO, VCCLVDS, and VCCPLL to maintain signal integrity and proper operation within the specified electrical limits.

Serializers, Deserializers Selection Notes

Select the MAX9218ECM/V+ when a robust LVDS deserializer is required for automotive or industrial video applications. This part pairs directly with the MAX9217 serializer to form a complete transmission link. Consider the ±2% reference clock tolerance and the ability to interface with 1.8V to 3.3V logic levels via the independent VCCO supply when designing the system architecture.

Serializers, Deserializers Part Context

This component belongs to the MAX9218 family of serializers and deserializers. It is specifically designed to work in tandem with the MAX9217 serializer. The device provides a complete solution for transmitting digital video data over long distances using twisted-pair cabling while maintaining low electromagnetic emissions and high noise immunity.

Serializers, Deserializers Replacement Considerations

The MAX9218ECM is a non-automotive qualified version of this component. The MAX9218ETM+ offers the same functionality but is packaged in a 48-lead Thin QFN format instead of LQFP. Verify pin compatibility and thermal requirements before substituting these variants.

Serializers, Deserializers FAQ

How does the MAX9218 handle control data transmission?

Control data is deserialized during the video blanking period. Five control inputs (C0-C4) use majority voting for single-bit-error tolerance, while C5-C8 are determined by their individual bit levels.

What is the function of the RNG0 and RNG1 pins?

These pins select the operating frequency range and corresponding output transition time. Setting them to specific states configures the device for either the 7MHz-to-15MHz range (slow transition) or the 15MHz-to-35MHz range (fast transition).

Can the outputs of multiple MAX9218 devices be connected together?

Yes, the outputs can be bused to form a multiplexer configuration. However, a delay of at least 30ns must be maintained between disabling one deserializer and enabling another to prevent output contention.
