Introduction and Features
The TW280X includes four high quality
NTSC/ PAL video decoders, which convert
analog composite to digital component
YCbCr for security application. The TW280X
contains four 10-bit A/D and proprietary
digital gain/clamp controllers and utilizes
proprietary techniques for separating lumin-
ance & chrominance to reduce both cross-
luminance and cross-chrominance artifacts.
The high performance dual scalers in each
channel offer two differently scaled video
outputs with 54MHz ITU-R BT.656 format
for security system design. Four built-in
motion detectors can also increase the
feature of security system.
Features
Accepts all NTSC (M/N/4.43) / PAL
(B/D/G/H/I/K/L/M/N/60) standard
formats with auto detection
Four 10-bit video CMOS analog to
digital converters
Adjust video level with proprietary
automatic clamp and gain control
system
Proprietary architecture for locking to
weak, noisy, or unstable signals
High performance adaptive comb filters
for all NTSC/PAL standards
IF compensation filter for improvement
of color demodulation
PAL delay lines for correcting PAL
phase errors
Programmable hue, saturation, contrast,
brightness and sharpness
Dual high quality horizontal and vertical
down scaler for each channel
Four built-in motion detectors for
security system
Supports the standard ITU-R BT.656 /
8bit ITU-R BT.601 format
Supports two differently scaled output
mode with 54MHz ITU-R BT.656 format
