SAA7114

     1 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 according

“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 BGDHIN, 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

– Increased luminance and chrominance bandwidth for

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 down-scaling and up-scaling 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 down scaling 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), North-American Broadcast Text

System (NABTS), close caption, Wide Screen Signalling

(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
