Description
Techwell’s TW9903 is a high-quality NTSC, PAL, and SECAM video decoder designed for multimedia applications. It uses mixed-signal 3.3V CMOS technology, providing a low-cost and low-power integrated solution. With its integrated analog front-end containing AGC, clamping, and three 8-bit high-speed ADCs, minimum external components are required. The decoder features an adaptive comb filter and luma/chroma processing for composite inputs, resulting in exceptionally high-quality pictures. It also includes a high-quality internal scaling engine for down-scaling the output picture and a built-in Closed-Caption decoder and VBI data pass-through for data applications.
