Description
The TW9990 is a high-quality electronic component designed for multimedia applications. It is a video decoder and down scaler that supports NTSC, PAL, and SECAM formats. The TW9990 utilizes advanced mixed-signal 3.3V CMOS technology to provide a low-cost and low-power integrated solution. With its integrated analog front-end, including AGC, clamping, and three 8-bit high-speed ADCs, the TW9990 requires minimal external components. It also features an adaptive comb filter, luma/chroma processing, and a high-quality internal scaling engine for exceptional picture quality. The TW9990 also includes a built-in closed-caption decoder and VBI data pass-through for data applications.
