Propagation Delay
The converter requires two clock rising edges for data to be
represented at the output. Each rising edge of the clock
captures the present data word and outputs the previous
data. The propagation delay is therefore 1/CLK, plus <2ns of
processing. See Figure 15.
Test Service
Intersil offers customer-specific testing of converters with a
service called Testdrive. To submit a request, fill out the
Testdrive form. The form can be found by doing an ‘entire
site search’ at www.intersil.com on the words ‘DAC
Testdrive’. Or, send a request to the technical support center.
