DETAILED FUNCTIONALITY

ANALOG FRONT END

• Four 140 MHz (ADV7403KSTZ-140), Noise Shaped Video,

12-bit ADCs enable true 10-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 antialias filters to remove out of band noise on

standard definition input video signals.

SDP PIXEL DATA OUTPUT MODES

• 8-/10-bit ITU-R BT.656 4:2:2 YCrCb with embedded time

codes and/or HS, VS, and FIELD

• 16-/20-bit YCrCb with embedded time codes and/or HS,

VS, and FIELD

• 24-/30-bit YCrCb with embedded time codes and/or HS,

VS, and FIELD

CP PIXEL DATA OUTPUT MODES

• Single data rate (SDR) 8-/10-bit 4:2:2 YCrCb for 525i, 625i

• Single data rate (SDR) 16-/20-bit 4:2:2 YCrCb for all

standards

• Single data rate (SDR) 24-/30-bit 4:4:4 YCrCb/RGB for all

standards

• Double data rate (DDR) 8-/10-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

• 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)

• Gemstar™ 1×/2× electronic program guide compatible

• Clocked from a single 28.63636 MHz crystal

• Subcarrier frequency lock (SFL) output for downstream

video encoder

• Differential gain typically 0.4%

• Differential phase typically 0.4°
