MAX9248ECM+T

Serializers, Deserializers Overview

The MAX9248ECM+T is a 27-bit DC-balanced LVDS deserializer operating at parallel clock frequencies from 5MHz to 42MHz. It converts serial video data into 18 bits of parallel RGB output and control data into 9 bits of CNTL output. The device features programmable ±2% or ±4% spread-spectrum modulation for EMI reduction, single-bit-error tolerant control inputs, and selectable rising or falling latch edges. It operates on a +3.3V core supply with a separate VCCO supply supporting 1.8V to 3.3V logic levels. Packaged in a 48-lead LQFP, it supports an industrial temperature range of -40°C to +105°C.

Serializers, Deserializers Feature Summary

• Proprietary decoding maintains DC balance for AC-coupling isolation
• Programmable spread-spectrum reduces electromagnetic interference
• Control data deserialized during video blanking intervals
• Single-bit-error tolerance on five control data inputs

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify the ECM suffix indicates the extended temperature range (-40°C to +105°C) rather than the commercial grade. Confirm the '+T' suffix denotes tape-and-reel packaging. Ensure the component matches the specific voltage and package requirements for the target automotive application before finalizing orders.

Serializers, Deserializers Selection Notes

Select this model when spread-spectrum capability is required for EMI mitigation. Use the MAX9250 variant if busing outputs is necessary instead of frequency spreading. Ensure the serializer provides a reference clock within ±2% tolerance. Verify that the interconnect length supports the desired bit-error rate at the selected operating frequency.

Serializers, Deserializers Part Context

This component belongs to the MAX9248/MAX9250 family of digital video serializers and deserializers. It pairs with the MAX9247 serializer to form a complete transmission system. The ECM designation specifies the industrial temperature rating, while the GCM variant offers a slightly different electrical profile. These devices are designed for robust automotive video interfaces.

Serializers, Deserializers Replacement Considerations

The MAX9248GCM+T is a compatible alternative with similar functionality but may have different electrical characteristics. The MAX9250ECM+T serves as a substitute if bus-compatible outputs are needed instead of spread-spectrum features. Verify pin compatibility and timing parameters before swapping.
