Featureseatures

      The TW9900 is a low power NTSC/PAL/SECAM video decoder chip that is designed for portable
applications. It consumes less than 100mW in t*ical composite input application. The available power
down mode further reduces the power consumption. It uses the 1.8V for both *og and di*al supply
voltage and 3.3V for I/O power. A single 27MHz crystal is all that needed to decode all *og video
standards.
         The video decoder decodes the base-band *og CVBS or S-video signals into di*al 8-bit 4:2:2
YCbCr for output. It consists of *og front-end with input source selection, variable gain amplifier and
*og-to-di*al 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 nonstandard signal as

well as weak signal. The output of the decoder is line-locked and formatted to the ITU-R 656 output with

embedded sync.
    The TW9900 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. It also detects copy-protected signal according to Macrovision standard including

AGC and colorstripe pulses.
     A 2-wire serial host interface is used to simplify system integration. All the functions can be controlled
through this interface.
