General description:

CDK3400/CDK3401 is a low-cost triple D/A converter that is tailored to fit graphics and video applications where speed is critical.

The CDK3400 offers 100MSPS sample rate, but CDK3401 offers 150MSPS sample rate.

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.
