The PELICAN SAA7112 is a video capture device for application at the image port of a VGA controller, with following feature highlights:
Video Decoder
l
Six analog inputs, internal analog source selectors, (e.g. 6 x CVBS or(2 x YC and 2 x CVBS) or (1x YC and 4 x CVBS)
l
Two analog preprocessing channels, including built in analog anti-alias filters
l
Fully programmable static gain for the main channels or Automatic Gain Control (AGC) for the selected CVBS/Y channel
l
Two 8 bit video CMOS Analog-to-Digital Converters (ADCs)
l
Automatic Clamp Control (ACC) for CVBS, Y and C
l
Switchable white peak control
l
On-chip line locked clock generation in accordance with CCIR-601
l
Digital PLL for synchronization and clock generation from all standards and non-standard video sources, e.g. consumer grade VTR
l
Requires only one crystal (32.11 MHz) for all standards
l
Horizontal and vertical sync detection
l
Automatic detection of 50/60Hz field frequency, and automatic switching between standards PAL and NTSC
l
Luminance and chrominance signal processing for PAL BGHI, PAL N, PAL M, NTSC M, NTSC N, NTSC 4.43 and SECAM
l
User programmable luminance peaking or aperture correction
l
Cross-colour reduction for NTSC by chrominance combination filtering
l
PAL delay line for correcting PAL phase errors
l
Real time status information output (RTCO)
l
Independent Brightness Contrast Saturation (BCS) adjustment for decoder part.
Video Scaler
l
Horizontal and vertical down-scaling and up-scaling to randomly sized windows
l
Horizontal and vertical scaling range: 2 (zoom) to 1/64 (icon); vertical zoom might be restricted
l
Anti-alias- and accumulating filter for horizontal scaling
l
Vertical scaling with linear phase interpolation (6-bit phase accuracy) and accumulating filter for anti-aliasing
l
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
l
Two independent programming sets for scaler part, to define two ‘ranges’ per field or per frame
l
Field-wise switching between decoder-part and expansion port input
l
Brightness, contrast and saturation controls for scaled outputs.
VBI-data decoder and text slicer
l
versatile VBI-data decoder, slicer, clock regeneration and byte synchronization; e.g. for WST, NABST, Close Caption, WSS, etc.
Audio clock generation
l
Generation of a field locked audio master clock to support a constant number of audio clocks per video field
l
Generation of an audio serial and left/right (channel) clock signal.
