MAX9247GCM/V+T

Serializers, Deserializers Overview

The MAX9247GCM/V+T is a digital video parallel-to-serial converter that serializes 27 bits of parallel data into a serial-data stream. It accepts 18 bits of RGB video data and 9 bits of control data, encoding them to reduce the serial-data rate while maintaining DC balance. The device operates with a parallel clock frequency ranging from 2.5MHz to 42MHz, corresponding to serial data rates up to 840Mbps. It features a +3.3V core supply and an input supply range of 1.71V to 3.6V for logic interfacing. The serializer includes an integrated 100Ω LVDS output termination and supports automotive qualification.

Serializers, Deserializers Feature Summary

• Proprietary data encoding ensures DC balance and reduces electromagnetic interference (EMI).
• Integrated preemphasis improves eye diagram quality and signal integrity at the output.
• Programmable phase-shifted LVDS signaling further reduces EMI emissions.
• Five control data inputs are designed with single-bit-error tolerance.

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates automotive grade qualification. Ensure the package type matches the required footprint for PCB integration. Check for RoHS compliance status if environmental regulations apply to the assembly process.

Serializers, Deserializers Selection Notes

Select this serializer when pairing with compatible deserializers like the MAX9248 or MAX9250 for digital video links. Ensure the application requires a parallel clock frequency between 2.5MHz and 42MHz. Verify that the system environment necessitates the -40°C to +105°C operating temperature range specified for the GCM variant.

Serializers, Deserializers Part Context

This component belongs to the MAX9247 series of serializers manufactured by Analog Devices / Maxim Integrated. It is part of a broader ecosystem of SerDes products designed for high-speed video transmission. The GCM/V+ designation specifically denotes the automotive qualified version in a 48-lead LQFP package with extended temperature capabilities.

Serializers, Deserializers Replacement Considerations

The MAX9247ECM/V+ serves as a lower temperature range alternative within the same package. For systems requiring deserialization, the MAX9248 or MAX9250 are the paired components. No direct pin-compatible replacements are documented for this specific serializer function.
