8-bit, 180MSPS, Triple Video DACs
General Description
CDK3405 is a low-cost triple D/A converter that is 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 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 1.25V
reference voltage can be overridden by the V
REF
input.
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.
