Maxim Integrated MAX9248ECM+T: High-Speed Serial Link Serializer

The MAX9248ECM+T from Maxim Integrated is a state-of-the-art serializer designed to interface with automotive video cameras. This compact and efficient IC is capable of serializing 27 bits of parallel data into a high-speed serial data stream. The primary application for this device is in the transmission of video and control data between a camera and a control unit in automotive environments, where reliable communication over long distances with minimal cabling is essential.

Key Features

• High Data Rate: The MAX9248ECM+T supports a high data rate of up to 2.5Gbps, making it suitable for high-resolution and high-frame-rate video applications.
• Reduced EMI: With its low electromagnetic interference (EMI) emission, the device is ideal for use in the electrically noisy environment of a vehicle.
• Embedded Control Channel: This serializer includes an embedded control channel, which operates at 9.6kbps to 1Mbps, allowing for bidirectional communication over the same differential pair.
• Spread Spectrum Capability: It supports spread spectrum clocking (SSC) for reduced EMI.
• Robust Error Detection: The device features a CRC (cyclic redundancy check) on the control channel and a parity bit for the video payload, enhancing data integrity.
• Automatic Coax Cable Equalization: The MAX9248ECM+T automatically compensates for cable loss, up to a certain length, ensuring signal integrity.

Applications

The MAX9248ECM+T is primarily designed for automotive applications, including:

• Automotive rear-view camera systems
• Surround-view camera systems
• Driver-assist cameras
• Other automotive video transmission systems

Additional Information

This serializer is offered in a 48-pin LQFP package and is specified over the -40°C to +105°C automotive temperature range. The MAX9248ECM+T also includes a programmable spread spectrum for the serial output and a programmable pre-emphasis level to compensate for cable losses. The device is designed for ease of use and reliability, making it a go-to solution for automotive video data transmission challenges.
