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 IO
G
output. BLANK
will override RGB inputs, setting IO
G
, IO
B
and IO
R
currents to zero when
BLANK = L. Although appropriate for many applications, the internal 1.235V
reference voltage can be overridden by the V
REF
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.
