TW9903-AAMB - Brand New TECHWELL/INTERSIL IC Chips
-
Description
The TW9903-AAMB is an IC chip manufactured by Techwell Inc. It is a high-quality NTSC, PAL, and SECAM video decoder with a built-in scaler. This chip is designed for multimedia applications and uses 3.3V CMOS technology, making it a low-cost and low-power integrated solution. With its integrated analog front-end, the TW9903-AAMB requires minimal external components. It features adaptive comb filtering and luma/chroma processing for superior picture quality. The chip also includes a high-quality internal scaling engine for downscaled output. Additionally, it has a built-in Closed-Caption decoder and supports VBI data pass-through for data applications.
