Typical Performance Data
The graph in Figure 7 shows representative
performance data of spurious free dynamic range
(SFDR) vs. output frequency performance measured
from TQ6124 devices.
Data was collected at room temperature; note,
however, that SFDR is not strongly dependendent on
temperature. Optimum performance is obtained by
utilizing as high a clock rate as practical.
