theoretically improving the even order harmonic rejection,
but likely reducing the signal swing available due to the
output voltage compliance range limitations.
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 at www.intersil.com/testdrive. Or, send a
request to the technical support center.
