MAX9257AGCM/V+GB

Serializers, Deserializers Overview

The MAX9257AGCM/V+GB is a fully programmable serializer designed for digital video serial links. It operates with the MAX9258A deserializer to serialize 10, 12, 14, 16, or 18 bits of parallel data into a high-speed serial stream. The device supports a maximum serial-data rate of 840Mbps and accommodates pixel clock frequencies ranging from 5MHz to 70MHz. It features an integrated bidirectional control channel over the same differential pair used for video data, eliminating the need for external CAN or LIN interfaces. The component utilizes LVDS I/O standards and includes programmable spread spectrum and preemphasis capabilities to optimize signal integrity over cable runs.

Serializers, Deserializers Procurement Notes

Verify the specific suffix GB against official documentation to confirm package type and tape-and-reel specifications. Confirm that the ordering code matches the required 48-pin LQFP form factor. Ensure compatibility with the paired MAX9258A deserializer for complete link functionality. Check for any recent product change notices affecting pinout or electrical characteristics.

Serializers, Deserializers Selection Notes

Select this serializer when a robust, programmable video link is required for automotive or industrial environments. Ensure the system design accounts for the separate core and I/O supply voltages. Verify that the cable length and preemphasis settings align with the desired data rate and signal integrity requirements. Consider the GPIO availability if peripheral control is needed directly through the serializer.
