Product Category: IC Chips
Product Details
Techwell’s TW9903 is a high quality NTSC, PAL, and SECAM video decoder plus high quality down scaler designed for multimedia applications. It uses the mixed-signal 3.3V CMOS technology to provide a low-cost and low-power integrated solution. Minimum external components are required due to its integrated analog front-end containing AGC, clamping, and three 8-bit high speed ADCs. For composite inputs, an adaptive comb filter and luma/chroma processing produce exceptionally high quality pictures using proprietary techniques. A high quality internal scaling engine offers arbitrarily filtered down scaling of the output picture. A built-in Closed-Caption decoder and VBI data pass-through support data applications such Closed-Captioning and IntercastÔ.
