TW8817-TA3-GR T&R

Video Processing Overview

The TW8817-TA3-GR T&R is a digital LCD panel processor integrating an NTSC/PAL/SECAM decoder and timing controller. It supports analog video inputs including CVBS and S-video, featuring adaptive 4H comb filtering and 2D de-interlacing. The device includes a built-in microcontroller with SPI, I2C, and UART interfaces. It drives digital single-pixel active matrix TFT panels up to WXGA (1280x768) resolution at 100MHz. Operating on 1.8V or 3.3V supplies, it features integrated CCFL and LED controllers, typical power consumption under 350mW, and is housed in an 80-pin TQFP package.

Video Processing Procurement Notes

Verify the specific TA3-GR suffix against official Intersil/Renesas documentation to confirm tape-and-reel packaging and grade specifications. Ensure compatibility with existing PCB footprints for the 80-pin TQFP package. Confirm that the 1.8V/3.3V operating voltage aligns with target system power rails. Validate that the integrated MCU peripherals meet project requirements for SPI, I2C, and UART connectivity.

Video Processing Selection Notes

Select this component for applications requiring a cost-effective solution combining analog TV decoding with direct digital LCD panel driving. It is suitable for portable devices where low power consumption below 350mW is critical. The integrated MCU reduces bill-of-materials by eliminating external control processors. Consider its support for multiple analog input formats when designing systems needing versatile video source compatibility.

Video Processing Part Context

This part belongs to the TW8817 family of digital LCD panel processors originally developed by Intersil Corporation, which was subsequently acquired by Renesas Electronics. These devices are designed to simplify LCD TV designs by integrating video decoding, processing, and panel driving functions into a single chip, reducing board space and complexity compared to discrete solutions.

Video Processing Replacement Considerations

Check for updated datasheets from Renesas as Intersil product lines may have successors. Verify pin-to-pin compatibility if substituting within the same family. Ensure any replacement maintains support for required analog standards and TFT panel resolutions.
