TW8806-PB2-GRS

Video Processing Overview

The TW8806-PB2-GRS is an LCD display processor manufactured by Renesas Electronics Corporation, formerly Intersil. It integrates a high-performance NTSC/PAL/SECAM video decoder with a TFT panel controller in a 128-pin PQFP package (14x20 mm). The device operates with a 1.8 V core and 3.3 V I/O supply voltage. It supports TFT panel resolutions up to 1280 x 768 pixels at one pixel per clock. The chip includes three analog-to-digital converters for YPbPr/RGB component inputs and accepts digital RGB or YCbCr signals.

Video Processing Feature Summary

• Integrated triple analog-to-digital converter supporting simultaneous multi-format input combinations
• Built-in de-interlacing engine and image-scaling capabilities for resolution conversion
• On-chip OSD RAM and closed caption decoder for flexible display management
• Programmable timing controller supporting digital and analog panel interfaces

Video Processing Applications

• Portable TV systems
• Rear seat car displays
• Portable DVD players
• Navigation and DVD combo units
• In-flight entertainment displays

Video Processing Procurement Notes

Verify the current status of this component as it is marked as obsolete or not recommended for new designs. Confirm availability through authorized distributors or surplus channels. Ensure that any replacement strategy accounts for the lack of pin compatibility with suggested successor models. Validate RoHS compliance and moisture sensitivity levels before integration into production workflows.

Video Processing Selection Notes

Select this component for applications requiring mixed-signal integration of TV decoding and TFT driving in a compact form factor. It is suitable for portable devices where low power consumption and small board space are critical constraints. Consider the specific input requirements, such as the need for multiple composite or component video sources, when evaluating its suitability against other display controllers.

Video Processing Part Context

This part belongs to the Techwells TW8806 series of LCD flat panel TV and PC monitor controllers. It was originally developed by Intersil Corporation before being acquired by Renesas Electronics. The series is designed to provide a cost-effective solution for standalone LCD displays by combining video processing and panel control logic into a single integrated circuit.

Video Processing Replacement Considerations

The datasheet recommends the TW8835 as a replacement part. However, it is explicitly noted that the TW8835 is not pin-compatible. Design modifications will be required if substituting this component, including PCB layout changes and potential firmware updates.
