Procurement Notes
Verify the component status as the datasheet explicitly states this product is not recommended for new designs. Confirm availability of the recommended replacement part TW8835, noting that it is not pin compatible. Ensure design updates accommodate the substitute component before procurement.
Selection Notes
Select this component for legacy designs requiring mixed-signal integration of TV decoding and TFT panel driving. Evaluate the need for external ADCs if utilizing digital RGB inputs for PC graphics. Consider the non-pin-compatible replacement TW8835 for any new development projects.
Part Context
The TW8804 is manufactured by Intersil Corporation, which has since been acquired by Renesas Electronics. This specific model represents a high-quality, low-cost solution for converting standard TV, DTV, and PC monitor signals into digital data for driving various TFT panel types.
Replacement Considerations
The datasheet recommends the TW8835 as the replacement part. Note that the TW8835 is not pin compatible, requiring schematic and layout modifications during substitution.
FAQ
What is the maximum supported TFT panel resolution?
The TW8804 supports TFT panel resolutions up to SXGA (1280 x 1024).
Does the TW8804 support interlaced video?
Yes, the chip includes an internal de-interlacing engine that allows interlaced video to be supported.
