FEATURES
1.1
Video acquisition/clock
Up to sixteen analog CVBS, split as desired (all of the
CVBS inputs optionally can be used to convert e.g.
Vestigial Side Band (VSB) signals)
Up to eight analog Y + C inputs, split as desired
Up to four analog component inputs, with embedded or
separate sync, split as desired
Four on-chip anti-aliasing filters in front of the
Analog-to-Digital Converters (ADCs)
Automatic Clamp Control (ACC) for CVBS, Y and C
(or VSB) and component signals
Switchable white peak control
Four 9-bit low noise CMOS ADCs running at twice the
oversampling rate (27 MHz)
Fully programmable static gain or Automatic Gain
Control (AGC), matching to the particular signal
properties
On-chip line-locked clock generation in accordance with
“ITU 601”
Requires only one crystal (32.11 or 24.576 MHz) for all
standards
Horizontal and vertical sync detection.
1.2
Video decoder
Digital PLL for synchronization and clock generation
from all standards and non-standard video sources e.g.
consumer grade VTR
Automatic detection of any supported colour standard
Luminance and chrominance signal processing for
PAL B, G, D, H, I and N, combination PAL N, PAL M,
NTSC M, NTSC-Japan, NTSC 4.43 and SECAM
Adaptive 2/4-line comb filter for two dimensional
chrominance/luminance separation, also with VTR
signals
– Increasedluminanceandchrominancebandwidthfor
all PAL and NTSC standards
– Reduced cross colour and cross luminance artefacts
PAL delay line for correcting PAL phase errors
Brightness Contrast Saturation (BCS) adjustment,
separately for composite and baseband signals
User programmable sharpness control
Detection of copy-protected signals according to the
macrovision standard, indicating level of protection
Independent gain and offset adjustment for raw data
path.
1.3
Component video processing
RGB component inputs

matrix.
1.4
Video scaler
Horizontal and vertical downscaling and upscaling to
randomly sized windows
Horizontal and vertical scaling range: variable zoom to
1
64
(icon) (note: H and V zoom are restricted by the
transfer data rates)
Anti-alias and accumulating filter for horizontal scaling
Vertical scaling with linear phase interpolation and
accumulating filter for anti-aliasing (6-bit phase
accuracy)
Horizontal phase correct up and downscaling for
improved signal quality of scaled data, especially for
compression and video phone applications, with 6-bit
phase accuracy (1.2 ns step width)
Two independent programming sets for scaler part, to
define two ‘ranges’ per field or sequences over frames
Fieldwise switching between decoder part and
expansion port (X-port) input
Brightness, contrast and saturation controls for scaled
outputs.
1.5
Vertical Blanking Interval (VBI) data decoder
and slicer
Versatile VBI-data decoder, slicer, clock regeneration
and byte synchronization e.g. for World Standard
Teletext (WST), North-American Broadcast Text
System(NABTS),closecaption,WideScreenSignalling
(WSS) etc.
