TW9918-AAPA1-GD - Brand New Techwell IC Chips
-
Description
The TW9918-AAPA1-GD is a low power NTSC/PAL/SECAM video decoder with VBI slicer. It supports automatic format detection for NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination), PAL (60), and SECAM. The decoder allows for software selectable analog inputs, such as 4 CVBS or 3 CVBS and 1 Y/C. It features a built-in analog anti-alias filter, two 10-bit ADCs, and programmable static gain or automatic gain control for the Y channel. With its advanced image enhancement capabilities, including peaking and CTI, it delivers high-quality video decoding. The TW9918-AAPA1-GD also includes a VBI slicer for industrial standard data services and supports ITU-R 601 or ITU-R 656 compatible YCbCr(4:2:2) output format.
