MAX9248GCM/V+T

Serializers, Deserializers Overview

The MAX9248GCM/V+T is a 27-bit DC-balanced LVDS deserializer operating at parallel clock frequencies from 5MHz to 42MHz. It converts a single LVDS serial input into 18 bits of parallel video data and 9 bits of parallel control data. The device features programmable spread-spectrum output for EMI reduction, selectable rising or falling latch edges, and an internal PLL. It operates on a +3.3V core supply with a separate VCCO supply supporting 1.8V to 3.3V logic levels. The component is housed in a 48-lead LQFP package and is specified for industrial temperature ranges.

Serializers, Deserializers Feature Summary

• Proprietary data decoding provides DC balance and reduces electromagnetic interference.
• Programmable spread-spectrum capability allows output data and clock frequency spreading to minimize EMI emissions.
• Control data is deserialized during video blanking periods to optimize bandwidth usage.
• Single-bit-error tolerance is provided for specific control data inputs through majority voting.

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify the GCM suffix indicates the extended -40°C to +105°C temperature range compared to standard ECM variants. Confirm the T suffix denotes tape-and-reel packaging if reel handling is required for assembly. Ensure the datasheet revision matches the design requirements for timing parameters.

Serializers, Deserializers Selection Notes

Select this model when spread-spectrum functionality is required for EMI compliance. Verify that the serializer counterpart supports the 27-bit format and compatible encoding scheme. Check that the target logic voltage levels are supported by the separate VCCO supply rail configuration.

Serializers, Deserializers Part Context

This component belongs to the MAX9248/MAX9250 family of digital video serial-to-parallel converters. It is designed to pair with the MAX9247 serializer to form complete transmission systems. The GCM variant specifically offers the wider industrial temperature range suitable for automotive environments.

Serializers, Deserializers Replacement Considerations

MAX9250GCM/V+T serves as a functional alternative lacking spread-spectrum but featuring output enable busing. MAX9248ECM+ is a lower-temperature variant within the same series. Cross-check pin compatibility and timing specifications before substitution.
