TW8807-LA2-GR

Video Processing Overview

The TW8807 is a TFT panel controller with an embedded NTSC/PAL/SECAM TV decoder and analog T-CON. It supports 1.8V and 3.3V operation, consuming less than 500mW typical power. The device features five analog inputs for CVBS or S-video signals, a 4H adaptive comb filter, and a built-in de-interlacing engine. It includes a multi-window OSD controller with alpha blending and programmable image enhancement functions such as sharpness and gamma control. The IC interfaces directly with analog active matrix TFT panels via integrated DACs and a timing controller.

Video Processing Procurement Notes

Verify the current datasheet status before design implementation. This component is marked as not recommended for new designs. Confirm that the Intersil datasheet version matches your specific revision requirements. Ensure compatibility with existing system architectures given the availability of replacement parts.

Video Processing Selection Notes

Select this component for legacy designs requiring integrated analog TV decoding and direct analog panel driving. It eliminates the need for separate decoders and timing controllers. Consider the 64-pin LQFP package constraints. Evaluate the single crystal requirement and low power consumption benefits for portable applications.

Video Processing Part Context

The TW8807 was manufactured by Intersil Americas LLC. It serves as a complete solution for adapting standard analog TV signals for display on various TFT LCD panel types. The device consolidates video processing, scaling, and panel driving functions into a single package to reduce bill of materials and PCB area.

Video Processing Replacement Considerations

The TW8833 is identified as the recommended replacement part. Note that the TW8833 is not pin compatible with the TW8807. Design modifications will be required for integration.
