General Description
CDK3400/3401 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: CDK3400 at 100MSPS and CDK3401 at 150MSPS.
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.
Few external components are required, just the current reference resistor,
current output load resistors, and decoupling capacitors.
Package is a 48-lead TQFP. Fabrication technology is CMOS. Performance is
guaranteed from 0 to 70°C.
