... Moisture sensitivity level for all parts is MSL-3. ©2009 CADEKA Microcircuits LLC General Description CDK3404 is a low-cost triple D/A converters that are tailored to fit graphics and video applications where speed is critical. 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 ...

... Data Sheet The CDK3404 may also be operated with a single 75Ω terminating resistor. To lower the output voltage swing to the desired range, the nominal value of the resistor on R should be doubled. REF R, G, and B Current Outputs - Current source outputs can drive VESA VSIS, and RS- 343A/SMPTE-170M compatible levels into doubly-termi- nated 75Ω ...

... The CDK3404 should be located near the board edge, close to the analog out-put connectors. 2. The power plane for the CDK3404 should be separate from that which supplies the digital circuitry. A single power plane should be used for all of the V the power supply for the CDK3404 is the same as that of the system’ ...
