DETAILED FUNCTIONALITY
ANALOG FRONT END
Four 140 MHz (ADV7403KSTZ-140), Noise Shaped Video,
12-bit ADCs enable true 10-bit video decoder
Rev. SpA | Page 13 of 24
12 analog input channel mux enables multisource
connection without the requirement of an external mux
Four current and voltage clamp control loops ensure any
dc offsets are removed from the video signal
SCART functionality and SD RGB overlay on CVBS
controlled by fast blank input
Four antialias filters to remove out of band noise on
standard definition input video signals.

COMPOSITE AND S-VIDEO PROCESSING
Support for NTSC (J, M, 4.43), PAL (B, D, I, G, H, M, N,
60) and SECAM B/D/G/K/L standards in the form of
CVBS and S-video
Superadaptive 2D 5-line comb filters for NTSC and PAL
give superior chrominance and luminance separation for
composite video
Full automatic detection and autoswitching of all
worldwide standards (PAL/NTSC/SECAM)
Automatic gain control with white peak mode ensures
the video is always processed without loss of the video
processing range
Adaptive digital line length tracking (ADLLT)
Proprietary architecture for locking to weak, noisy, and
unstable sources from VCRs and tuners
IF filter block compensates for high frequency luma
attenuation due to tuner SAW filter
Chroma transient improvement (CTI)
Luminance digital noise reduction (DNR)
Color controls include hue, brightness, saturation, contrast,
and Cr and Cb offset controls
Certified Macrovision copy protection detection on
composite and S-video for all worldwide formats
(PAL/NTSC/SECAM)
4× oversampling (54 MHz) for CVBS, S-video, and YUV
modes
Line-locked clock output (LLC)
Letterbox detection supported
Free-run output mode provides stable timing when no
video input is present
Vertical blanking interval data processor
TeleText
Video Programming System (VPS)
Vertical Interval Time Codes (VITC)
Closed captioning (CC) and extended data service
(EDS)
Wide screen signaling (WSS)
Copy generation management system (CGMS)
