MAX9247ETM+T

Serializers, Deserializers Overview

The MAX9247ETM+T is a digital video parallel-to-serial converter that serializes 27 bits of parallel data into a serial-data stream. It encodes and multiplexes 18 bits of video data and 9 bits of control data onto the serial interface, reducing the serial-data rate. The device operates from a +3.3V core supply with a separate input supply for interfacing to 1.8V to 3.3V logic levels. It features an integrated 100 Ω LVDS output termination and supports frequencies from 2.5MHz to 42MHz. The component is available in a 48-lead LQFP package and is specified for operating temperatures ranging from -40°C to +85°C or -40°C to +105°C.

Serializers, Deserializers Feature Summary

• Proprietary data encoding reduces EMI and provides DC balance
• Preemphasis improves eye diagram and signal integrity at the output
• Programmable phase-shifted LVDS signaling reduces EMI
• ISO 10605 and IEC 61000-4-2 Level 4 ESD protection

Serializers, Deserializers Applications

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

Serializers, Deserializers Procurement Notes

Verify the specific temperature grade suffix when ordering. The 'E' suffix indicates the -40°C to +85°C range, while the 'G' suffix denotes the -40°C to +105°C automotive-grade variant. Confirm the exact part number matches the required thermal specification for the target application environment before finalizing procurement.

Serializers, Deserializers Selection Notes

Select the MAX9247ETM+T for applications requiring a serializer paired with MAX9248/MAX9250 deserializers. Ensure the system clock frequency falls within the 2.5MHz to 42MHz range. Verify that the interconnect medium supports the required data rates and that AC-coupling capacitors are sized appropriately based on the parallel clock frequency to maintain signal integrity.

Serializers, Deserializers Part Context

The MAX9247ETM+T belongs to the Maxim Integrated MAX9247 series of serializers. It is designed to work in conjunction with MAX9248 or MAX9250 deserializers to form a complete digital video serial link. This pairing allows for efficient transmission of video and control data over twisted-pair cables or controlled-impedance PCB traces.

Serializers, Deserializers Replacement Considerations

The MAX9247ECM+ serves as the standard commercial-grade replacement for the same functionality within the -40°C to +85°C temperature range. For automotive applications requiring extended temperature support, the MAX9247GCM+ is the appropriate alternative.
