FEATURES
1.1
Video decoder
Six analog inputs, internal analog source selectors, e.g.
6
×
CVBS or (2
×
Y/C and 2
×
CVBS) or (1
×
Y/C and
4
×
CVBS)
Two analog preprocessing channels in differential
CMOS style inclusive built-in analog anti-alias filters
Fully programmable static gain or Automatic Gain
Control (AGC) for the selected CVBS or Y/C channel
Automatic Clamp Control (ACC) for CVBS, Y and C
Switchable white peak control
Two 9-bit video CMOS Analog-to-Digital Converters
(ADCs), digitized CVBS or Y/C signals are available on
the expansion port
On-chip line-locked clock generation in accordance with
“ITU 601”
Digital PLL for synchronization and clock generation
from all standards and non-standard video sources e.g.
consumer grade VTR
Requires only one crystal (32.11 or 24.576 MHz) for all
standards
Horizontal and vertical sync detection
Automatic detection of 50 and 60 Hz field frequency,
and automatic switching between PAL and NTSC
standards
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:
– Increasedluminanceandchrominancebandwidthfor
all PAL and NTSC standards
– Reduced cross colour and cross luminance artefacts
PAL delay line for correcting PAL phase errors
Independent Brightness Contrast Saturation (BCS)
adjustment for decoder part
User programmable sharpness control
Independent gain and offset adjustment for raw data
path.
1.2
Video scaler
Horizontal and vertical downscaling and upscaling to
randomly sized windows
Horizontal and vertical scaling range: variable zoom to
1
64
(icon) (it should be noted that the 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.
1.3
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),NorthAmericanBroadcastTextSystem
(NABTS),closecaption,WideScreenSignalling(WSS),
etc.
1.4
Audio clock generation
Generation of a field-locked audio master clock to
support a constant number of audio clocks per video
field
Generation of an audio serial and left/right (channel)
clock signal.
