MAX9218ETM+

Serializers, Deserializers Overview

The MAX9218ETM+ is a digital video serializer/deserializer (SerDes) component manufactured by Analog Devices Inc./Maxim Integrated. It functions as a DC-balanced LVDS deserializer designed to convert serial data into parallel outputs. The device operates with a parallel clock frequency ranging from 7MHz to 35MHz, supporting a maximum serial data rate of 700Mb/s. It accepts a single LVDS differential input and provides 27 parallel LVTTL/LVCMOS outputs, divided into 18 bits for RGB video data and 9 bits for control signals. The unit requires a +3.0V to +3.6V supply voltage and is specified for an operating temperature range of -40°C to +85°C. It is housed in a 48-lead Thin QFN package.

Serializers, Deserializers Feature Summary

• Control data is deserialized during the video blanking period to optimize bandwidth usage.
• Supports AC coupling between the transmitter and receiver to provide electrical isolation.
• Features selectable rising or falling output latch edges for flexible system integration.

Serializers, Deserializers Applications

• Navigation System Displays
• In-Vehicle Entertainment Systems
• Video Cameras
• LCD Displays

Serializers, Deserializers Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the ETM+ designation corresponds to the 48-lead Thin QFN variant. Confirm RoHS compliance status through official manufacturer documentation before procurement. Check current production status, as availability may vary based on manufacturing lifecycle updates.

Serializers, Deserializers Selection Notes

Select this component when a high-speed LVDS deserialization solution is required for automotive or industrial video applications. Ensure the system design accommodates the separate power domains for VCC, VCCO, VCCLVDS, and VCCPLL. Verify that the external reference clock frequency falls within the supported 7MHz to 35MHz range for proper PLL locking.

Serializers, Deserializers Part Context

The MAX9218ETM+ belongs to the MAX9218 family of DC-balanced LVDS serializers and deserializers. It is specifically engineered to pair with the MAX9217 serializer to form a complete digital video transmission system. This pairing allows for robust video data transfer over twisted-pair cables while minimizing EMI through proprietary encoding techniques.

Serializers, Deserializers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official resources for potential obsolescence management or alternative component recommendations.

Serializers, Deserializers FAQ

How does the MAX9218 handle control data transmission?

Control data is deserialized during the video blanking time. The DE_OUT signal indicates whether RGB_OUT or CNTL_OUT outputs are active.

What is the purpose of the RNG inputs?

The RNG inputs select the operating frequency range and determine the output transition times. They must be set to match the serializer's parallel clock input frequency.

Can the outputs of multiple MAX9218 devices be connected together?

Yes, the outputs can be bused to form a multiplexer configuration using the OUTEN pin. A delay of at least 30ns is required between disabling one device and enabling another to avoid contention.
