MAX9248ECM+

Serializers, Deserializers Overview

The MAX9248ECM+ is a digital video serial-to-parallel converter (deserializer) from the MAX9248/MAX9250 family. It deserializes 27 bits, converting an LVDS serial input into 18 bits of parallel video data and 9 bits of control data. The device operates at parallel clock frequencies between 5MHz and 42MHz with a maximum serial data rate of 840Mb/s. It features programmable spread-spectrum output for EMI reduction, proprietary DC-balanced decoding, and AC-coupling support. Powered by a +3.3V core supply and a separate VCCO supply for 1.8V to 3.3V logic interfacing, it is housed in a 48-lead LQFP package and specified for industrial temperatures from -40°C to +105°C.

Serializers, Deserializers Feature Summary

• Programmable ±4% or ±2% spread-spectrum capability on data and clock outputs to reduce electromagnetic interference.
• Proprietary data decoding ensures DC balance, enabling AC-coupling for galvanic isolation between transmitter and receiver.
• Separate video and control phases utilize video timing to minimize required serial-data rates.
• Single-bit-error tolerance for five control data inputs using majority voting during the control phase.

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify the specific suffix 'ECM+' against the manufacturer's current datasheet revision to confirm the operating temperature range (-40°C to +105°C) and package type (48-lead LQFP). Confirm that the component meets RoHS compliance standards as indicated in the official documentation. Check for any recent product discontinuation notices or lifecycle status updates directly from Analog Devices/Maxim Integrated before finalizing procurement plans.

Serializers, Deserializers Selection Notes

Select the MAX9248ECM+ when spread-spectrum output is required for EMI mitigation in automotive video links. Ensure the application frequency falls within the 5MHz to 42MHz range supported by the ECM variant. Verify compatibility with the MAX9247 serializer for complete transmission systems. Consider the MAX9250 if busing capabilities are needed instead of spread-spectrum features.

Serializers, Deserializers Part Context

The MAX9248ECM+ belongs to the MAX9248/MAX9250 series of 27-bit DC-balanced LVDS deserializers designed for automotive digital video applications. It pairs primarily with the MAX9247 serializer, though it can also interface with the MAX9217 serializer for frequencies below 35MHz. This component completes the digital video transmission chain by recovering parallel RGB and control data from a serialized LVDS stream.

Serializers, Deserializers Replacement Considerations

The MAX9248GCM+ is a verified alternative within the same family, offering identical functionality but specified for commercial temperature ranges (-40°C to +85°C). Designers must verify that the thermal requirements of their application align with the GCM variant's specifications before substitution.
