FMS3110/3115 Triple Video D/A Converters 3 x 10 bit, 150 Ms/s Features - - - - - - - - - - 10-bit resolution 150 megapixels per second ± 0.1% linearity error Sync and blank controls 1.0V p-p video into 37.5Ω or 75Ω load Internal bandgap voltage reference Double-buffered data for low distortion TTL-patible inputs Low glitch energy Single +5 Volt power supply Description FMS3110/3115 products are low-cost triple D/A converters that are tailored to fit graphics and video applications where speed is critical. Two speed grades are available: FMS3110 FMS3115 100 Ms/s 150 Ms/s Applications - Video signal conversion - RGB - YCBCR - posite, Y, C - Multimedia systems - Image processing - True-color graphics systems (1 billion colors) - Broadcast television equipment - High-Definition Television (HDTV) equipment - Direct digital synthesis TTL-level inputs are converted to analog current outputs that can drive 25- 37.5Ω loads corresponding to doubly-terminated 50- 75Ω loads. A sync current following SYNC input timing is added to the IOG output. BLANK will override RGB inputs, setting IOG, IOB and IOR currents to zero when BLANK = L. Although appropriate for many applications the internal 1.235V reference voltage can be overridden by the VREF input. Few external ponents are required, just the current reference resistor, current output load resistors, and decoupling capacitors. Package is a 48-lead LQFP. Fabrication technology is CMOS. Performance is guaranteed from 0 to 70°C. Block Diagram SYNC BLANK SYNC G9-0 10 bit D/A Converter B9-0 10 bit D/A Converter R9-0...
