Zarlink Semiconductor Inc.
(See Figures 9a, 9b, 9c)
* Typical figures are at 25
°
C with nominal
±
5V supplies. For design aid only: not guaranteed and not subject to production testing.
Note 3:
The filter characteristics are totally dependent upon the accuracy of the clock frequency providing F1i is synchronized to
C2i. The A/D and D/A functions are unaffected by changes in clock frequency.
Note 4:
This gives a 75 ns period, 50 ns before and 25 ns after the 50% point of C2i rising edge, when change in F1i
will give an
undetermined state to the internally synchronized enable signal.
