DETAILED FUNCTIONALITY
ANALOG FRONT END
• Four high quality 10-bit ADCs enable true 8-bit video
decoder
• 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 internal antialias filters to remove out-of-band noise
on standard definition input video signals
SDP PIXEL DATA OUTPUT MODES
• 8-bit ITU-R BT.656 4:2:2 YCrCb with embedded time
codes and/or HS, VS, and FIELD
• 16-bit YCrCb with embedded time codes and/or HS, VS,
and FIELD
• 24-bit YCrCb with embedded time codes and/or HS, VS,
and FIELD
CP PIXEL DATA OUTPUT MODES
• Single data rate (SDR) 8-bit 4:2:2 YCrCb for 525i, 625i
• Single data rate (SDR) 16-bit 4:2:2 YCrCb for all standards
• Single data rate (SDR) 24-bit 4:4:4 YCrCb/RGB for all
standards
• Double data rate (DDR) 8-bit 4:2:2 YCrCb for all standards
• Double data rate (DDR) 12-bit 4:4:4 YCrCb/RGB for all
standards
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

COMPONENT VIDEO PROCESSING
• Formats supported include 525i, 625i, 525p, 625p, 720p,
1080i, and many other HDTV formats
• Automatic adjustments include gain (contrast) and offset
(brightness); manual adjustment controls are also
supported
• Support for analog component YPrPb/RGB video formats
with embedded sync or with separate HS, VS, or CS
• Any-to-any, 3 × 3 color space conversion matrix supports
YCrCb-to-RGB and RGB-to-YCrCb
• Standard identification (STDI) enables system level
component format detection
• Synchronization source polarity detector (SSPD) deter-
mines the source and polarity of the synchronization
signals that accompany the input video
• Certified Macrovision copy protection detection on
component formats (525i, 625i, 525p, and 625p)
• Free-run output mode provides stable timing when no
video input is present
• Arbitrary pixel sampling support for nonstandard video
sources
RGB GRAPHICS PROCESSING
• 140 MSPS conversion rate supports RGB input resolutions
up to 1280 × 1024 @ 75 Hz (SXGA); (110 MSPS conversion
rate for ADV7401BSTZ-110); (80 MSPS conversion rate for
ADV7401BSTZ-80)
• Automatic or manual clamp and gain controls for graphics
modes
• Contrast and brightness controls
• 32-phase DLL allows optimum pixel clock sampling
• Automatic detection of sync source and polarity by SSPD
block
• Standard identification is enabled by STDI block
• RGB can be color space converted to YCrCb and
decimated to a 4:2:2 format for video centric backend IC
interfacing
• Data enable (DE) output signal supplied for direct
connection to HDMI/DVI Tx IC
• Arbitrary pixel sampling support for nonstandard video
sources
DIGITAL VIDEO INPUT PORT
