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

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 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.
