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
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.
APPLICATIONS
n Video signal conversion
– RGB
– YCBCR
– Composite, Y, C
n Multimedia systems
n Image processing
n PC Graphics
Few external components are required, just the current reference resistor,
current output load resistors, bypass capacitors, and decoupling capacitors.
Package is a 48-lead TQFP. Fabrication technology is CMOS. Performance is
guaranteed from -40°C to +125°C.
