TIMING EXAMPLES
For the AD7276, if CS is brought high during the 14
th SCLK rising
edge after the two leading zeros and 12 bits of the conversion
have been provided, the part can achieve the fastest throughput
rate, 3 MSPS. If CS is brought high during the 16
th SCLK rising
edge after the two leading zeros and 12 bits of the conversion
and two trailing zeros have been provided, a throughput rate of
2.97 MSPS is achievable. This is illustrated in the following two
timing examples.
Timing Example 1
In Figure 6, using a 14 SCLK cycle, fSCLK = 48 MHz and the
throughput is 3 MSPS. This produces a cycle time of t2 +
12.5(1/fSCLK) + tACQ = 333 ns, where t2 = 6 ns minimum and
tACQ = 67 ns.
This satisfies the requirement of 60 ns for tACQ. Figure 6 also
shows that tACQ comprises 0.5(1/fSCLK) + t8 + tQUIET, where
t8 = 14 ns max. This allows a value of 43 ns for tQUIET, satisfying
the minimum requirement of 4 ns.
Timing Example 2
The example in Figure 7 uses a 16 SCLK cycle, fSCLK = 48 MHz,
and the throughput is 2.97 MSPS. This produces a cycle time of
t2 + 12.5(1/fSCLK) + tACQ = 336 ns, where t2 = 6 ns minimum and
tACQ = 70 ns. Figure 7 shows that tACQ comprises 2.5(1/fSCLK) + t8 +
tQUIET, where t8 = 14 ns max. This satisfies the minimum
requirement of 4 ns for tQUIET.
