Timing Example 1
Having FSCLK = 18 MHz and a throughput rate of 1 MSPS gives a
cycle time of
1/Throughput = 1/1,000,000 = 1 μs
A cycle consists of
t2 + 12.5(1/FSCLK) + tACQ = 1 μs
Therefore, if t2 = 10 ns
10 ns + 12.5(1/18 MHz) + tACQ = 1 μs
tACQ = 296 ns
This 296 ns satisfies the requirement of 290 ns for tACQ.
2.5(1/FSCLK) + t8 + tQUIET
where t8 = 35 ns. This allows a value of 122 ns for tQUIET,
satisfying the minimum requirement of 60 ns.
Timing Example 2
Having FSCLK = 5 MHz and a throughput rate of 315 kSPS gives a
cycle time of
1/Throughput = 1/315,000 = 3.174 μs
A cycle consists of
t2 + 12.5(1/FSCLK) + tACQ = 3.174 μs
Therefore, if t2 is 10 ns
10 ns + 12.5(1/5 MHz) + tACQ = 3.174 μs
tACQ = 664 ns
This 664 ns satisfies the requirement of 290 ns for tACQ.
2.5(1/FSCLK) + t8 + tQUIET
where t8 = 35 ns. This allows a value of 129 ns for tQUIET,
satisfying the minimum requirement of 60 ns.
As in this example and with other slower clock values, the signal
may already be acquired before the conversion is complete, but
it is still necessary to leave 60 ns minimum tQUIET between
conversions. In Timing Example 2, the signal should be fully
acquired at approximately Point C in Figure 40.
