TIMING EXAMPLES
Figure 6 and Figure 7 show some of the timing parameters from
the Timing Specifications section.
Timing Example 1
As shown in Figure 7, when fSCLK = 5 MHz and the throughput is
250 kSPS, the cycle time is
t2 + 12.5(1/fSCLK) + tACQ = 4 µs
With t2 = 10 ns minimum, then tACQ is 1.49 µs, which satisfies
the requirement of 290 ns for tACQ.
In Figure 7, tACQ is comprised of 2.5(1/fSCLK) + t10 + tQUIET, where
t10 = 30 ns maximum. This allows a value of 960 ns for tQUIET,
satisfying the minimum requirement of 30 ns.
Timing Example 2
The AD7921 can also operate with slower clock frequencies. As
shown in Figure 7, when fSCLK = 2 MHz and the throughput rate
is 100 KSPS, the cycle time is
t2 + 12.5(1/fSCLK) + tACQ = 10 µs
With t2 = 10 ns minimum, then tACQ is 3.74 µs, which satisfies
the requirement of 290 ns for tACQ.
In Figure 7, tACQ is comprised of 2.5(1/fSCLK) + t10 + tQUIET, where
t10 = 30 ns maximum. This allows a value of 2.46 µs for tQUIET,
satisfying the minimum requirement of 30 ns.
In this example, as with other slower clock values, the signal
might already be acquired before the conversion is complete,
but it is still necessary to leave 30 ns minimum tQUIET between
conversions. In this example, the signal should be fully acquired
at approximately point C in Figure 7.
