MAX9257AGCM/V+

Serializers, Deserializers Overview

The MAX9257AGCM/V+ is a fully programmable serializer designed to pair with the MAX9258A deserializer. It serializes 10, 12, 14, 16, and 18-bit parallel data into LVDS signals at rates up to 840Mbps. The device features an integrated bidirectional control channel for UART/I2C communication over the same differential pair used for video data. It operates from a +3.3V core supply (VCC) and supports I/O levels from +1.71V to +3.3V (VCCIO). Key electrical parameters include a parallel clock frequency range of 5MHz to 70MHz and an operating temperature range of -40°C to +105°C.

Serializers, Deserializers Feature Summary

• Integrated bidirectional control channel enables UART or I2C communication over the same differential pair as video data, eliminating external interface requirements.
• Programmable parallel data width accommodates various pixel formats, supporting 10, 12, 14, 16, and 18-bit configurations.
• DC-balanced coding scheme allows for AC-coupling in the serial link while reducing inter-symbol interference.
• Supports programmable spread spectrum and preemphasis settings to optimize signal integrity over cable lengths up to 20m.

Serializers, Deserializers Applications

• Automotive cameras
• Industrial cameras
• Navigation systems display
• In-vehicle entertainment systems

Serializers, Deserializers Procurement Notes

Verify the specific package variant, as the MAX9257A family includes both 40-lead TQFN and 48-pin LQFP options. Confirm that the ordering suffix corresponds to the required physical footprint and pinout configuration for your PCB layout. Ensure compatibility with the paired MAX9258A deserializer for system integration.

Serializers, Deserializers Selection Notes

Select this component when a serializer is required to interface with the MAX9258A deserializer in a SerDes application. Consider the 48-pin LQFP package for designs requiring higher pin counts or specific thermal characteristics compared to the 40-lead TQFN option. Verify that the I/O voltage requirements align with the system's logic levels.

Serializers, Deserializers Part Context

Serializers, Deserializers FAQ

How does the control channel operate?

The integrated control channel transfers data bidirectionally at power-up during video blanking over the same differential pair used for video data, supporting both UART and I2C protocols.

What is the maximum serial data rate supported?

The MAX9257A supports a maximum serial-data rate of 840Mbps when paired with the MAX9258A deserializer.

Can the device support AC-coupled links?

Yes, the device uses DC-balanced coding which reduces ISI and allows for AC-coupling in the serial link.
