CDK3402/CDK3403
8-bit, 100/150MSPS, Triple Video DACs

FEATURES n 8-bit resolution n 150 megapixels per second n linearity error n Sync and blank controls n 1.0Vpp video into or 75Ω load n Internal bandgap voltage reference n Double-buffered data for low distortion n TTL-compatible inputs n Low glitch energy n Single +5V power supply

CDK3402/3401 products are low-cost triple D/A converters that are tailored to fit graphics and video applications where speed is critical. Two speed grades are available CDK3402 at 100MSPS and CDK3403 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.

Few external components are required, just the current reference resistor, current output load resistors, and decoupling capacitors.
