Features
Analog Video Decoder
Techwell's TW9919 is a high quality NTSC/PAL/SECAM video decoder
that is designed for multimedia applications. It uses the mixed-signal
2.5V/3.3V CMOS technology to provide a low-power integrated solution.
The TW9919 analog front-end is equipped with six separate analog
channels that enable it to accept various analog video input standard
including Composite video, S-video, component video (YCbCr), and SCART
RGB. With the analog FB support, it also allows the mixing of composite or
S-video input with YCbCr/RGB input. All channels include an analog
multiplexer (MUX) for maximum flexibility in software controlled input
selection. It is possible to connect up to five composite inputs or two S-
video inputs or two YCbCr inputs or two SCART RGB inputs at one time and
allow the software to switch between them. Alternatively, a maximum
combination of five of these inputs may be switched under software
control. In the PIP mode, a maximum combination of four composite/S-
video input can be mixed with any of two YCbCr/RGB inputs through
The front-end contains all the necessary circuits to simplify the system
design. The built-in six high quality 10-bit analog-to-digital converters
(ADCs)

The TW9919 uses proprietary adaptive 3D comb filter to achieve best NTSC
and PAL quality fpr stationary portion. For motion part of the image, it
employs 2H(NTSC)/4H(PAL) comb filter for chroma and luma separation to
achieve high video quality. The image enhancement includes horizontal
The advanced synchronization processing can produce stable pictures for
non-standard signal such as those produced by VCR trick mode.
The high quality scaler uses multi-tap poly-phase decimation filter to
accurately scale down the image with minimum phase error. It can be
programmed to scale-down the output picture to an arbitrary ratio with
The TW9919 supports flexible pixel interface. It outputs YCbCr (4:2:2) data
stream over 10-bit or 20-bit data path. It also supports both free-running
