Overview

The TW9910-NA2-GR is a low power NTSC/PAL/SECAM video decoder chip that is designed for portable applications. It consumes less than 100mW in typical composite input application. The available power down mode further reduces the power consumption. It uses the 1.8V for both analog and digital supply voltage and 3.3V for I/O power. A single 27MHz crystal is all that needed to decode all analog video standards.The video decoder decodes the base-band analog CVBS or S-video signals into digital 8 or 16-bit 4:2:2 YCbCr for output. It consists of analog front-end with input source selection, variable gain amplifier and analog-to-digital converters, Y/C separation circuit, multi-standard color decoder (PAL BGHI, PAL M, PAL N, combination PAL N, NTSC M, NTSC 4.43 and SECAM) and synchronization circuitry. The Y/C separation is done with high quality adaptive 4H comb filter for reduced cross color and cross luminance. The advanced synchronization processing circuitry can produce stable pictures for non-standard signal as well as weak signal. A video scaler is provided to arbitrarily scale down the output video in a packed format. The output of the decoder is line-locked and formatted to the ITU-R 656 output with embedded sync.The TW9910-NA2-GR also includes circuits to detect and process vertical blanking interval (VBI) signal. It slices and process VBI data for output through video bus. Some information can also be alternatively retrieved through host interface.A 2-wire serial host interface is used to simplify system integration. All the functions can be controlled through this interface.
