Video Decoder
The TW9910 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
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
The TW9910 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
A 2-wire serial host interface is used to simplify system integration. All the
