Product data sheet Rev. 02 — 6 December 2007 2 of 90 NXP Semiconductors SAA7154E; SAA7154H Multistandard video decoder with comb filter The decoded video (the digitized component video, respectively) can be output on an 8-bit or 10-bit wide ITU-656 expansion port (X-port); alternatively decoded video can be fed to a versatile video scaler to the Image port (I-port), which can be 8-bit, 16-bit or 24-bit wide. An analog On-Screen Display (OSD) interface allows to mix OSD data on the I-port and X-port video data; the digital OSD allows to add OSD data to the I-port video data. 2. Features 2.1 General I Sixteen analog input pins, allowing for multiple combinations of composite, s-video and component video I Eight 3-level capable sensor pins for D-connector or SCART AV- and RGB-switch signals (three of these can be active simultaneously); one fast blanking input I Four studio-quality 10-bit CMOS ADCs at four-fold ITU-656 oversampling (54 MHz) I I2C-bus read back of digital Automatic Gain Control (AGC) gain factor I Two buffered analog CVBS outputs, e.g. to drive teletext decoder or VCR recorder I Several D-terminal and SCART configurations possible I Level sensitive fast blanking (RGB switch control) I Multistandard video decoder PAL/SECAM/NTSC and their sub-standards I Automatic detection of any supported color standard, including 480p, 576p, 720p and 1080i component video I Optional digitizing of VGA (640 × 480) computer graphics with H-sync and V-sync (supports only 60 Hz vertical sync) I Detection of copy protected input signals according to the Macrovision standard, indicating level of protection, including progressive signals 480p and 576p I High-performance super-adaptive 2⁄4-line comb filter for 2-dimensional chrominance/luminance separation I HD0 component video input and output; detection of HD0/HD1 signals I Horizontal and vertical down-scaling and up-scaling to randomly sized windows; variable from zoom to 1 ⁄ 64 size (icon); the transfer data rates limit H-zoom and V-zoom: N Conversion to square pixel format N Vertical scaling with linear phase interpolation and accumulating filter for anti-aliasing (6-bit phase accuracy) N EDge-Guided vertical Interpolation (EDGI) used for zooming up to progressive line counts I Versatile Brightness-Contrast-Saturation (BCS) adjustment I Programmable picture improvements: N Blue stretching N Green enhancement N Automatic skin tone correction N Color Transient Improvement (CTI) N Black and white stretching by histogram evaluation N Luminance sharpness control I RMS noise level estimation possible I Blue screen output in case of absent input signals |
