Two speed grades are available: CDK3402 at 100MSPS and CDK3403 at 150MSPS. 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 TQFP. Fabrication technology is CMOS. Performance is guaranteed from 0 to 70°C.
