11 / 20 page  ADV7181C Rev. 0 | Page 11 of 20 DETAILED FUNCTIONALITY ANALOG FRONT END The analog front-end section contains four high quality 10-bit ADCs, and the six analog input channel mux enables multisource connection without the requirement of an external mux. It also contains • Four current and voltage clamp control loops to ensure that any dc offsets are removed from the video signal • SCART functionality and SD RGB overlay on CVBS that are 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-/10-bit ITU-R BT.656 4:2:2 YCrCb with embedded time codes and/or HS, S, and FIELD • 16-/20-bit YCrCb with embedded time codes and/or HS, VS, and FIELD CP PIXEL DATA OUTPUT MODES CP pixel data output modes include single data rate (SDR) and double data rate (DDR) as follows: • SDR 8-/10-bit 4:2:2 YCrCb for 525i, 625i • SDR 16-/20-bit 4:2:2 YCrCb for all standards • DDR 8-/10-bit 4:2:2 YCrCb for all standards • DDR 12-bit 4:4:4 RGB for graphics inputs COMPOSITE AND S-VIDEO PROCESSING Composite and S-Video processing features offer support for NTSC M/J, NTSC 4.43, PAL B/D/I/G/H, PAL60, PAL M, PAL N, and SECAM (B, D, G, K, and L) standards in the form of CVBS and S-Video as well as super-adaptive, 2D, 5-line comb filters for NTSC and PAL give superior chrominance and luminance separation for composite video. They also include full automatic detection and autoswitching of all worldwide standards (PAL, NTSC, and SECAM) and automatic gain control with white peak mode to ensure the video is always processed without loss of the video processing range. Other features are • Adaptive Digital Line Length Tracking (ADLLT™) • Proprietary architecture for locking to weak, noisy, and unstable sources from VCRs and tuners • IF filter block to compensate for high frequency luma attenuation due to tuner SAW filter • Chroma transient improvement (CTI) • Luminance digital noise reduction (DNR) • Color controls including 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 support • Free-run output mode to provide stable timing when no video input is present • Vertical blanking interval data processor, including teletext, video programming system (VPS), vertical interval time codes (VITC), closed captioning (CC) and extended data service (EDS), wide screen signaling (WSS), copy genera- tion management system (CGMS), and compatibility with GemStar™ 1×/2× electronic program guide • Clocked from a single 28.63636 MHz crystal • Subcarrier frequency lock (SFL) output for downstream video encoder • Differential gain typically 0.5% • Differential phase typically 0.5° |
