Two speed grades are available CDK3400 at 100MSPS and CDK3401 at 150MSPS. TTL-level inputs are converted to analog current outputs that can drive 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.
