Features
Video Decoder
The TW9900 is Techwell’s next generation low-cost multi-standard 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-bit 4:2:2 YCbCr for output. It consists of analog front-end
with input source selection, variable gain amplier 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 lter 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. 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.
