VSP9402A Allgemeine Beschreibung

IntroductionThe VSP 94x2A (PRIMUS) is a new component of the Micronas MEGAVISION® IC set in a CMOS embedded DRAM technology. The VSP 94x2A comprises all main functions of a digital featurebox in one monolithic IC. The number of features is limited in favor of a lowcost solution, but no trade-off has been made concerning picture quality.Features– Integrated video matrix switch    • Up to seven CVBS inputs, up to two Y/C inputs,    • Three CVBS outputs (Y/C inputs signals are combined to CVBS output format)    • 9 bit amplitude resolution for CVBS, Y/C A/D converter    • AGC (Automatic Gain Control)– Multi-standard color decoder    • PAL/NTSC/SECAM including all substandards    • Automatic recognition of chroma standard    • Only one crystal necessary for all standards– RGB-FBL or YUV-H-V input    • 8 bit amplitude resolution for RGB or YUV    • 8 bit amplitude resolution for FBL or H– ITU656 support (version dependent, refer to next chapter)    • ITU656 input/output    • DS656 output (double-scan ‘656-like’ output)– Letterbox detection– Noise reduction    • Temporal noise reduction    • Field-based temporal noise reduction for luminance and chrominance    • Different motion detectors for luminance and chrominance or identical    • Flexible programming of the temporal noise reduction parameters    • Automatic measurement of the noise level– Horizontal scaling of the 1fH signal    • Split-screen possible with additional PiP or Text processor– Flexible digital horizontal scaling of the 2fH signal    • Scaling factors: 3, ., 0.75 including 16:9 compatibility    • 5 zone panorama generator– Embedded memory    • On-chip memory controller    • Embedded DRAM core for field memory    • SRAM for PAL/SECAM delay line– Data format 4:2:2– Flexible clock and synchronization concept    • Horizontal line-locked or free-running mode    • Vertical locked or free-running mode(Continue .)
