CDK3404
FEATURES
General Description n 8-bit resolution, 180MSPS n ±2.5% gain matching n ±0.5% linearity error n Sync and blank controls n 1.0Vpp video into 37.5Ω or 75Ω load n Internal bandgap voltage reference n Low glitch energy n Single +3.3V power supply
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 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 1.25V reference voltage can be overridden by the VREF input.
