Timing Example 1  
From Figure 6, having fSCLK = 52 MHz and a throughput of 3MSPS, gives a cycle time of t2 + 12.5(1/fSCLK) + tACQ  
333 ns. With t2 = TBD ns min, this leaves tACQ to be TBD ns. This TBD ns satisfies the requirement of TBD ns for  
=
tACQ. Figure 6 shows that, tACQ comprises of 2.5(1/fSCLK) + t8 + tQUIET, where t8 = TBD ns max. This allows a value of  
TBD ns for tQUIET satisfying the minimum requirement of TBD ns.  
Timing Example 2  
Having fSCLK = 20 MHz and a throughput of 1.5 MSPS, gives a cycle time of t2 + 12.5(1/fSCLK) + tACQ = 666 ns.  
With t2 = TBD ns min, this leaves tACQ to be TBD ns. This TBD ns satisfies the requirement of TBD ns for tACQ. From  
Figure 6, tACQ comprises of 2.5(1/fSCLK) + t8 + tQUIET, where t8 = TBD ns max. This allows a values of TBD ns for  
tQUIET satisfying the minimum requirement of TBD ns.
