CMOS-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 1.25V reference voltage can be overridden by the VREF input. Few external components are required, just the current reference resistor, current output load resistors, bypass capacitors, and decoupling capacitors. Package is a 48-lead TQFP. Fabrication technology is CMOS. Performance is guaranteed from -40°C to +125°C. 8-bit resolution, 180MSPS ±2.5% gain matching ±0.5% linearity error Sync and blank controls 1.0Vpp video into 37.5Ω or 75Ω load Internal bandgap voltage reference Low glitch energy Single +3.3V power supply APPLICATIONS Video signal conversion – RGB – YCBCR – Composite, Y, C n n n n Multimedia systems Image processing PC Graphics Block Diagram SYNC BLANK SYNC Rev 3A G7-0 8 8-bit D/A Converter IO G B7-0 8 8-bit D/A Converter IO B R7-0 CLOCK 8 ...
