www.fairchildsemi.com FMS3810/3815 Triple Video D/A Converters 3 x 8 bit, 150 Ms/s Features 8-bit resolution 150 megapixels per second – 0.2% 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-compatible inputs Low glitch energy Single +5 Volt power supply Description FMS3810/3815 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: FMS3810 FMS3815 100 Ms/s 150 Ms/s Applications Video signal conversion – RGB – YCBCR – Composite, Y, C Multimedia systems Image processing True-color graphics systems 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 components 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 G7-0 8 8 bit D/A Converter IOG B7-0 8 8 bit D/A Converter IOB R7-0 CL...
